Now the two functions are implemented differently in every BC, and the solver would also execute different things out according to each BC type defined. Thanks for corrections and improvement. peter. WebOpenFOAM can be used to solve equations governed by theory of elasticity (solid mechanics) as well. This equation can be solved in OpenFOAM by: fvVectorMatrix UEqn ( rho * fvm::d2dt2 (U) == fvm::laplacian (2*mu + lambda, U) + fvc::div ( - (mu + lambda) * gradU + lambda * tr (gradU)*I + (sigma & gradU) ) );
