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 ? |
