First, I need to compute the cylinder case by Compressible solver, then use the result of Compressible solver as the source of Acoustic solver. But how can I get the Lamb vector in CFD simulation? I think the Lamb vector in 2D is zero, am I right？ Could someone give me some advice? With best regards
