Hi forks,
I am trying to solve a equation like this, fvm::d2dt2(Qaplha,T) + fvm::ddt(Ralpha,T) - fvm::ddt(tauT,T) // this is new term represents ddt(tau,laplacian(T)) - fvm::laplacian(con, T) The red line is a 3 order differential term which OF cannot solve, in my opinion, a mix application from fvm::ddt and fvc::laplacian may be helpful, however, a fatal error was also produced, see lines in red below! codes has been implemented into Errors Message: new cannot satisfy memory request. This does not necessarily mean you have run out of virtual memory. It could be due to a stack violation caused by e.g. bad use of pointers or an out of date shared library I believe there is something wrong with tmp<ddtScheme<Type>> which is responsible for managing temporary objects, but I can not figure it out. Hoping to hear your suggestions. |
