Setting Solver Parameters and Stopping Criteria

Training Guide > Porous Media Flow Tutorials > Orthotropic Porous Media Tutorial > Setting Solver Parameters and Stopping Criteria

To promote rapid convergence, the velocity under-relaxation factor will be increased from 0.7 to 0.8.

Open the Solvers and Segregated Flow nodes, then select the Velocity node.

In the Properties window, change the Under-Relaxation Factor to 0.8.

The stopping criterion based on the upstream pressure monitor will be disabled and the analysis run for 120 iterations instead.

Open the Stopping Criteria node and select the Average Upstream Pressure Monitor Criterion node.

In the Properties window, deselect the Enabled property.

Select the Maximum Steps node and change the Maximum Steps to 120 in the Properties window.

Save the simulation.
