Meshing errors

Please login with a confirmed email address before reporting spam

Hello,

I am trying to run a parametric sweep with 2 parameters and i am facing a couple of problems during my simulation and i would be very pleased if you could help me.

The first error is:
Failed to evaluate variable.
- Variable: material.k21
- Geometry: 1
- Domain: 18
Failed to evaluate variable.
- Variable: mod1.ht.kyx
- Defined as: material.k21
Failed to evaluate variable.
- Variable: mod1.ht.k_effyx
- Defined as: mod1.ht.kyx
Failed to evaluate expression.
- Expression: d((-(mod1.ht.k_effxx*mod1.Tx+mod1.ht.k_effxy*mod1.Ty+mod1.ht.k_effxz*mod1.Tz)*test(mod1.Tx)-(mod1.ht.k_effyx*mod1.Tx+mod1.ht.k_effyy*mod1.Ty+mod1.ht.k_effyz*mod1.Tz)*test(mod1.Ty)-(mod1.ht.k_effzx*mod1.Tx+mod1.ht.k_effzy*mod1.Ty+mod1.ht.k_effzz*mod1.Tz)*test(mod1.Tz))*(dvol),{test@4})

And when I erased the Domain 18 to see what happen i face the second error.

The second error is:
A problem arose when building mesh feature 'Free Tetrahedral 1'.
Failed to generate mesh for domain.
- Domain: 1
Failed to insert point.
- x-coordinate: -413.356
- y-coordinate: -50.4578
- z-coordinate: -103
Internal error in mesh initialization.
- Detail: Failed to determine cavity.
Error in multiphysics compilation


Unfortunately i can't attached the file because of its size.

Thank you in advance for your help and your precious time,

Michalis

You can probably attach the file if you clear all the studies (top ribbon).
