Hi Experts,
I'm trying to simulate an acoustic structure interaction. It's 2 rooms ( cylindre ) seperated by a window, and i want to calculate the Sound Transmission Loss between these rooms.
After setting up materials and B.Cs , i used triangular mesh, then i tried to launch the simulaion eventhough i have 3 warnings for the mesh ( as far as i know, the simulation cannot be influenced by warnings )
When i try to compute i receive this error message : - - Feature: Stationary Solver 1 (sol1/s1) Failed to find a solution for the initial parameter. Segregated Step 1 System matrix is zero. In Segregated Step 1: Returned solution is not converged. Not all parameter steps returned.
I'm new to the field, so i'm really sory if my question isnt clear enough,
Thank you for your time,
Yasser
