Function Mapping and Deformation-Driven Equilibrium

[notatallaguru]

I am currently exploring the functionality of Python in combination with Ansys Mechanical and have a couple of questions regarding specific functionalities. Your guidance would be greatly appreciated in clarifying these points.

1. Mapping Function-Derived Temperature and Pressure Fields onto a Surface: I am interested in using my custom function to calculate pressure and temperature values (p(x,y) T(x,y)) and use these as a boundary condition in Mechanical. My wish is to map these computed values onto a specific surface within the Ansys Mechanical. Is this possible?

2. Deformation-Driven Updates and Equilibrium Position: I am exploring the feasibility of using deformation data to dynamically update the pressure and temperature values derived from the aforementioned function. My aim is to simulate a scenario where deformation influences temperature and pressure fields, eventually converging to an equilibrium position. Could you please inform me if this functionality can be achieved?

Thank you in advance for your assistance.

Hello @notatallaguru

I believe what you say it should be possible. Presumably you mean the following workflow.

- Create model (material, mesh, etc)
- Apply boundary conditions
- Solve to time 0
For i in range(time):
    - set time equal to i
    - get temperature (check mapdl.queries)
    - get displacements
    - apply boundary conditions
    - solve
Read final results
Further post-processing

It should be possible

I appreciate your prompt reply. This is what I mean, yes.

It's also not a problem to map the temperature and pressure using an equation?

Hi @notatallaguru Can you please clarify which product you are asking about. Ansys (Workbench) Mechanical is not Mechanical APDL. It seems that you are asking about Workbench [WB] Mechanical. Which has its own PyMechanical language library and GitHub page. And this is an much different problem in WB Mechanical than it is in Mechanical APDL.

For question 1 the answer is yes for PyMAPDL. For PyMechanical the answer is I'm pretty sure no, not yet. In 'standard' WB Mechanical mapping of load/bc data involves both WB Mechanical and WB External Data component system. PyMechanical is instancing a stand-alone version of Mechanical, which requires additional development to support such things as imported loads. As Mechanical would need the functionality that Extenal Data now provides. The stand-alone version of Mechanical does not yet have all the imported loads that external data supports...but they are being added!

For question 2 what @germa89 outlined should work with PyMAPDL.
