The project involves testing out of the various numerical settings in the incompressible analysis of airfoil.
When i set the value of all the relaxation parameters to 0.7, the simulation run ends with a floating point exception error. My initial values for the turbulence parameters are set to a non-zero value. The solver used for pressure is PCG and numerical schemes are predominantly linear. A sharp change in the residual of K is observed before the error.
The template of the project is based on Reference
The convergence plot is as shown below
I would like to know what results in the floating point exception error and what would be the possible corrections to my simulation.
