AcuSolve: Default pressure setting

Recommended Posts

Hi!

Who know what is default pressure in AcuSolve?
If I want to do a simulation at atmospheric pressure 1 atm (101325 Pa), do I need to enter the value in any section? such as at absolute pressure offset or pressure initial condition (in Nodal Initial Condition)??

Thanks

If you are doing incompressible both these settings are not required.
Absolute pressure offset would be necessary for compressible cases likes workshop5 compressible nozzle.

Nodal Initial conditions for pressure are generally not required. NIC typically help in convergence. Generally I would use them for temperature and eddy viscosity (at times for velocity, it is a flow only in one direction).
