Error while setting up porous material.
 

Hi,all
system:Linux, CFX571
problem: As I run a porous simulation with fan( a momentum source), it shows error message after 1st iteration:
<font color=green size=2>
| ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| Subsystem zone not found in SYMASS_ZONE </font>

But as I cancel the porous setting(<font color=blue> note: the model and cfx_pre file are the same as previous except the porous subdomain deleted</font>), then it will be OK .
Does anybody know why?

solved!
 

It's due to nature of CFX571, nothing to do with the setup and model. Because I put it into CFX10 , and it's ok now !
