Hi Will, Thanks for your interest in PyFR.
Does it mean that for fully incompressible fluid, artificial compressibility should be "ac-zeta = 0.0” ? No. You need some artificial compressibility for the approach to work. 1. How can I continue my simulation from the latest time step? You can restart from a .pyfrm/.pyfrs file (pyfr restart mesh.pyfrm solution.pyfrs) - see the User Guide online. 2. Is it able to map the flow field from one case to another case, even regardless the difference of mesh? (Something like "mapFileds" in OpenFOAM) No. 3. Is there any command in PyFR that we can export all .pyfrs files to .vtu files at once rather than export one time step by one time step? There have been other threads on this. For various reasons, it is best just to write a quick BASH script. 4. The output file is ".vtu", which is unreadable by text readers. Is there any command to export readable text file such as vtk, csv or text for the entire fluid field for post-processing? (Pretty similar to the output "U" and "p" file in OpenFOAM) 5. I am quite not sure what "[solver-dual-time-integrator-multip]" is in dual-time-stepping solvers, since it is deletable and simulation becomes much faster when it is deleted. Which simulation?
