Solver Failure due to Negative Volumes

When setting up a monitoring point, the solver uses the vertex closest to the monitoring point coordinates that you have defined and suggestions for avoiding mesh folding (i.e. negative volumes):
- Use a different Mesh Stiffness option. The default option may not be appropriate for your particular model.
- Modify the Model Exponent. If negative volumes are occurring on the boundaries, increase the exponent. If negative volumes are occurring away from the boundaries, try reducing it from the default value.
- Use the double precision solver
- Set the convergence criteria for the Mesh Displacement equation to a lower value (e.g. 1E-05) and increase the coefficient loops to 10 or higher in CFX-Pre under Solver Control->Equation Class Settings->Mesh Displacement
