Tutorial for Porous media (BIOT Theory)

Vikrant

Hello, 

I am working on one NVH Project. There I have fluid-stucture coupling. Now I have introduced a porous media to check the absorbing effect. 

Unfotunately, I couldn't find any tutorial for this application. Could anyone here, please share me the method to Setup this FE-Model. 

 

I have a Problem modelling solid-foam-fluid alltogether. 

 

Thanks in advance.

Please find attached sample model for BIOT.Please also look at the user’s guide section of BIOT.

Thanks Rahul for the material. I will have quick look in it. 

Vikrant

Thanks for the material. Now I have succesfully created BIOT propeties. 

I am trying to implement BIOT material layer in fluid-structure coupling (Infinite element method). 

 

But I am getting an error 

----------------------------------------------------------------------

 *** ERROR # 2986 ***
 Multiple modal space with BIOT material is not allowed.
 
 This error occurs in module 'prpdrv'.

----------------------------------------------------------------------

I couldn't find any solution regarding this error.

Hi, 
May I ask, How does it look? 

What are the possible changes i can make? 

 

Thanks.

Hi, 

This problem has been solved. 
Problem: 2 Modal simulations were defined. Normal modes and Frequecy Response. 
So  I deleted one  EIGRL card. and then it worked. 

 

Thanks for the support.
