本人在修改求解器过程中需要植入一个新的压力泊松方程,形式如下所示,方程来自文献。试了多次,但都没有成功,感觉是方程植入形式的问题,求助各位大佬指点,该方程应该怎么植入,谢谢啦
@strive_dut
surfaceScalarField phiHbyA = mesh.Sf() & fvc::interpolate(HbyA); fvc::ddt(rho) + psi*correction(fvm::ddt(p)) + fvc::div(rho, phiHbyA) - fvm::laplacian(rhobyAf, p)
@李东岳 感谢李老师百忙之中指点!这么来看correction(fvm::ddt(p))就代表前后时间步压力差值的时间变化率啦
correction(fvm::ddt(p))
