      计算一个对称的平板绕流,速度场和涡量大小的云图都对称,利用如下公式计算另一个变量的时候,计算出来的等值面不对称(应该是轻微不对称,但是我现在十分不对称),请问各位大佬,可能有什么原因呢。

      	surfaceScalarField phiw
      	(
      		"phiw",
                      fvc::flux(omega) * LL
      	);
      	
      
      	for (int ntau = 1; ntau <= 5; ntau++)
      	{
      		H.oldTime() = H;
      		fvScalarMatrix HEqn
      		(
      	             	  fvm::ddt(H)
      			+ fvm::div(phiw,H)
      			- fvm::laplacian(DH,H)
      		);
      		HEqn.solve();
      	}
