How can I assign a temperature boundary condition to a set of nodes in Simlab?

FranciscoRamirez

Hello experts!

I am trying to solve a steady state heat transfer problem in a solid using Simlab and Optistruct as a solver. I have a simple meshed part as shown below:

and I want to impose a prescribed temperature (e.g. 500 K) on the nodes selected (orange points on the image above). However, Simlab gives only two options (file:///C:/Program%20Files/Altair/2022.3/SimLab/hwx/help/SimLab/english/topics/analysis/ThermalTemperature.htm):

1. Temperature on faces/edges
2. Distributed temperature table

The second option seems to solve my problem, but I need to know the nodal coordinates of the nodes, as shown below:

or nodes IDs, as shown below:

When I select the nodes, I can see the list of nodes with their IDs:

Thus, I can manually enter 336 node IDs and their value, one by one. This can be a challenging task, even for a small problem like mine. Thus, the questions are:

• Can I export the list of selected nodes in Simlab? This is because the value can be assigned more quickly in a spreadsheet and then imported into Simlab.
• Is there any way within Simlab to assign a temperature to the selected nodes directly, as in many other CAE software?

Hello Adriano,

I tried to break the face, but the following error appears:

The other options (Edge, Vertex, etc) are not possible because I have a mesh imported from an .inp file.

Additionally, how to do the other tip (the other option is meant for distribution of space varying temperature)?

 

if it is a solid, then you can 'break' the solid body into smaller regions using this 'from solid elem', first, and then create smaller faces, so that you can select them for applying temperatures.
