# Example Thermal Transient Analysis¶

This example shows how you can use PyMAPDL to input a time dependent temperature table to vary the temperature at a beam. This uses convection loads with independently varying convection coefficient and bulk temperature.

mapdl = launch_mapdl(loglevel="ERROR")

mapdl.clear()
mapdl.prep7()

## Geometry and Mesh¶

Create a block 5x1x1 inches in size and mesh it

```mapdl.block(0, 5, 0, 1, 0, 1)
mapdl.lesize("ALL", 0.2, layer1=1)

mapdl.mshape(0, "3D")
mapdl.mshkey(1)
mapdl.vmesh(1)
mapdl.eplot()
```

## Setup the Solution¶

Solve a transient analysis while ramping the load up and down.

Note the solution time commands in the above code fragment. The final TIME is set to 1000 seconds. Time substep size is permitted to range from a minimum of 2 seconds to a maximum of 50 seconds in the DELTIM command. A first substep of 10 seconds is applied. Automatic time substep sizing will vary substeps between the extremes.

A Table Array is used for the time-dependent Convection Coefficient values. Times go in the Zeroth column, while associated Convection Coefficients go in the First column.

```mapdl.run("/SOLU")
mapdl.antype(4)  # transient analysis
mapdl.trnopt("FULL")  # full transient analysis
mapdl.kbc(0)  # ramp loads up and down

# Time stepping
end_time = 1500
mapdl.time(end_time)  # end time for load step
mapdl.autots("ON")  # use automatic time stepping

# setup where the subset time is 10 seconds, time
mapdl.deltim(10, 2, 25)  # substep size (seconds)
#                          -- minimum value shorter than smallest
#                            time change in the table arrays below

# Create a table of convection times and coefficients and transfer it to MAPDL
my_conv = np.array(
[
[0, 0.001],  # start time
[120, 0.001],  # end of first "flat" zone
[130, 0.005],  # ramps up in 10 seconds
[700, 0.005],  # end of second "flat zone
[710, 0.002],  # ramps down in 10 seconds
[end_time, 0.002],
]
)  # end of third "flat" zone

# Create a table of bulk temperatures for a given time and transfer to MAPDL
my_bulk = np.array(
[
[0, 100],  # start time
[120, 100],  # end of first "flat" zone
[500, 300],  # ramps up in 380 seconds
[700, 300],  # hold temperature for 200 seconds
[900, 75],  # temperature ramps down for 200 seconds
[end_time, 75],
]
)  # end of second "flat" zone
```

## The Transient Thermal Solve¶

This model is to be solved in one time step. For this reason, a `TSRES` command is used for force the solver to include a `SOLVE` at every time point in the two Table Arrays above. This ensures that the time-dependent curves are followed by the transient analysis. Intermediate solutions between the `TSRES` time points will be included according to the `DELTIM` command and the automatic time stepping decisions of the ANSYS solver.

In this example, the times for the `TSRES` array illustrated above have been determined manually. A set of APDL commands could be used to automate this process for chosen Table Array entries, in more complex modeling situations, including checks that no time intervals are too short.

Results at substeps will be wanted if the intermediate solutions of the time-transient analysis are to be available for post-processing review. The `OUTRES` command is used to control how much is written to the results file. In this example the OUTRES command will be used to simply write out all results for all substeps. In work with large models and may substeps, too much data will be written if such a strategy is employed for `OUTRES`, and other options will need to be considered. Note that one option for the `OUTRES` command is to control times at which results are written with a Table Array, much as is used in the `TSRES` command, but typically for a larger number of time points, although including those of the TSRES array.

The initial condition starting temperature is controlled for this example with the `TUNIF` command. Note that thermal transient analyses can also have a starting temperature profile formed by a static thermal `SOLVE`. If a user neglects to set an initial temperature in ANSYS Mechanical APDL, a value of zero will be used, which is often not what is desired.

The thermal convective loads are applied with an SF family command—in this example a convective load is applied to the end face of the solid model by the SFA command, using the Table Array entries for convection and bulk temperature that were developed above. The Table Array names are surrounded with percent signs (%). A SOLVE is then performed.

```# Force transient solve to include the times within the conv and bulk arrays
# my_tres = np.unique(np.vstack((my_bulk[:, 0], my_conv[:, 0])))[0]  # same as
mapdl.parameters["my_tsres"] = [120, 130, 500, 700, 710, 900, end_time]
mapdl.tsres("%my_tsres%")

mapdl.outres("ERASE")
mapdl.outres("ALL", "ALL")

mapdl.eqslv("SPARSE")  # use sparse solver
mapdl.tunif(75)  # force uniform starting temperature (otherwise zero)

# apply the convective load (convection coefficient plus bulk temperature)
# use "%" around table array names
mapdl.sfa(6, 1, "CONV", "%my_conv%", " %my_bulk%")

# solve
mapdl.solve()
```

## Post-Processing¶

Open up the result file using `ansys.mapdl.reader` result = mapdl.thermal_result

```mapdl.post1()
```

Out:

```'FINISH SOLUTION PROCESSING\n\n\n ***** ROUTINE COMPLETED *****  CP =        99.033\n\n\n\n *** ANSYS - ENGINEERING ANALYSIS SYSTEM  RELEASE 2021 R2          21.2BETA ***\n Ansys Mechanical Enterprise                       \n 00000000  VERSION=LINUX x64     15:29:23  JAN 21, 2022 CP=     99.034\n\n                                                                               \n\n\n\n ** WARNING: PRE-RELEASE VERSION OF ANSYS 21.2BETA\n  ANSYS,INC TESTING IS NOT COMPLETE - CHECK RESULTS CAREFULLY **\n\n          ***** ANSYS RESULTS INTERPRETATION (POST1) *****'

## Visualize a Slice¶

Visualize a slice through the dataset using `pyvista` for more details visit <https://docs.pyvista.org/>`_.

```# get the temperature of the 30th result set
mapdl.set(1, 30)
temp = mapdl.post_processing.nodal_temperature()

# Load this result into the underlying VTK grid
grid = mapdl.mesh._grid
grid["temperature"] = temp

# generate a single horizontal slice slice along the XY plane
single_slice = grid.slice(normal=[0, 0, 1], origin=[0, 0, 0.5])
single_slice.plot(scalars="temperature")
```

Out:

```/opt/hostedtoolcache/Python/3.8.12/x64/lib/python3.8/site-packages/pyvista/core/dataset.py:1401: PyvistaDeprecationWarning: Use of `point_arrays` is deprecated. Use `point_data` instead.
warnings.warn(
warnings.warn(
```

## Visualize Several Slices¶

This shows how you can visualize a series of slices through a dataset

```# get the temperature of a different result set
mapdl.set(1, 120)
temp = mapdl.post_processing.nodal_temperature()

# Load this result into the underlying VTK grid
grid = mapdl.mesh._grid
grid["temperature"] = temp

# generate a single horizontal slice slice along the XY plane
slices = grid.slice_along_axis(7, "y")
slices.plot(scalars="temperature", lighting=False, show_edges=True)
```

Out:

```/opt/hostedtoolcache/Python/3.8.12/x64/lib/python3.8/site-packages/pyvista/core/dataset.py:1401: PyvistaDeprecationWarning: Use of `point_arrays` is deprecated. Use `point_data` instead.
warnings.warn(
warnings.warn(
```

## Temperature at a Single Point¶

Extract the temperature at a single node and plot it with respect to the input temperatures using `ansys.mapdl`

Here, we use the `get_value` command which is very similar to the `*GET` command, except it immediately returns the value as a python accessible variable, rather than storing it to a MAPDL value.

```# for example, the temperature of Node 12 is can be retrieved simply with:
mapdl.get_value("node", 12, "TEMP")

# note that this is similar to # *GET, Par, NODE, N, Item1, IT1NUM, Item2, IT2NUM
# See the MAPDL reference for all the items you can obtain using *GET
```

Out:

```251.05408986663676
```

Here, we extract the temperature of the node across for each solution

```nsets = mapdl.post_processing.nsets
node_temp = []
for i in range(1, 1 + nsets):
mapdl.set(1, i)
node_temp.append(mapdl.get_value("node", 12, "TEMP"))

# here are the first 10 temperatures
node_temp[:10]
```

Out:

```[76.27707675716556, 76.81799224351983, 77.42151540097551, 79.04838835561239, 81.19108300049324, 83.56709007016165, 85.35125295387647, 86.2326642927535, 86.97754017604865, 88.31275589884443]
```

Alternatively, you can simply grab the data for the node from the entire response. This is less efficient as the entire data set is sent back for each result.

```# get the index of node 12 in MAPDL
idx = np.nonzero(mapdl.mesh.nnum == 12)[0][0]

# get the temperature at that index for each result
node_temp_from_post = []
for i in range(1, 1 + nsets):
mapdl.set(1, i)
node_temp_from_post.append(mapdl.post_processing.nodal_temperature()[idx])

# Again, the first 10 temperatures
node_temp_from_post[:10]
```

Out:

```[76.27707675716556, 76.81799224351983, 77.42151540097551, 79.04838835561239, 81.19108300049324, 83.56709007016165, 85.35125295387647, 86.2326642927535, 86.97754017604865, 88.31275589884443]
```

Plot the temperature as a function of time

```time_values = mapdl.post_processing.time_values
plt.plot(time_values, node_temp, label="Node 12")
plt.plot(my_bulk[:, 0], my_bulk[:, 1], ":", label="Input")
plt.legend()
plt.xlabel("Time (seconds)")
plt.ylabel("Temperature (\$^\circ\$F)")
plt.show()
```
