Hi all,

I could need a help for this problem as shown below:

+--------------------------------------------------------------------+
| Newton's method warnings at: END OF TIME STEP |
+--------------------------------------------------------------------+

+--------------------------------------------------------------------+
| |
| Newton's method failed to converge while computing the variables |
| listed below. In each case, the solver continued with the variable |
| field as it was on the final iteration. |
| |
| If this situation persists, you might try decreasing the Newton |
| iteration underrelaxation factor. This can be changed by setting |
| one of the following parameters for your mixture: |
| |
| Temperature : "Constitutive Relation Under Relaxation" |
| Pressure : "Newton Pressure Under Relaxation" |
| |
+--------------------------------------------------------------------+
| |
| Location Name : Default Fluid Porous Interface |
| Mesh location : ZIF1/IP |
| Routine : GET_PRESIP_ZIF_GEN |
| Variable Name : Static Pressure |
| Last 3 Changes : 3.31711E+00 3.05733E+00 3.15108E+00 |
| Tolerance : 1.0000E+00 |
| Status : STALLED |
| Max Iterations : 150

I did try to run the domain without porosity and it was successfully converged. Any ideas about above problem ?
