Hello to all,
I need to perform an RF frequency domain analysis on a waveguide which has been previously deformed by a Thermal Stress stationary analysis.
In order to do this, I need to calculate the new coordinate x,y,z (after the thermal stress induced displacement) using a moving mesh module.
I configured a Thermal stress module with all the needed conditions, to compute temperature T and deformation u,v,w.
In order to verify the used settings, I computed this step and the the deformation has been well calculated so that the waveguide has been deformed by the heating (excluding the fixed constraints boundaries) showing deformation and, using a boundary probe, I verify the computation of u, v, and w.
Then I inserted a Moving Mesh module, in which I set "Prescribed mesh displacement" on all boundaries, with dx=u, dy=v and dz=w (in order to use the previous step results). I insert a "free deformation" block in which I set to zero the initial values: dx0=0 dy0=0 and dz0=0 for all domains. In the default "fixed Mesh" block, all domains have been overridden.
This module has been assigned to a Stationary step in the same study.
After few seconds, it generates the following error:
Failed to evaluate expression.
- Expression: X+mod1.u-x
Failed to evaluate variable.
- Variable: mod1.u
- Geometry: 1
- Boundary: 3 10
Have you any suggestions to help me configuring the right coupling between these modules?
Thanks in advance.
Alberto
