I created a new class base openfoam ,and I used this class to calculate but the result show that the interface of process is discontinuous (as the picture shows). Maybe I should add some interprocess communication, and I want to know does openfoam has relevant casa.

hjasak will become famous soon enough
Please do reconstructPar and try to visualise the reconstructed case. It is likely, this is just due to the way Paraview reads decomposed data, ie, unlike FOAM, it does not do proper interpolation across processor boundaries.

Dear Professor Jasak

Thank you so much for your reply,maybe I should explain my problem more clearly,as the picture shows, they are the date(fIB) of processor 0 , processor 1 , after do reconstructPar and serial calculation respectively in paraview .
figure 3 and 4 show that there is big difference between serial calculation and parallel calculation . And i found that my problem is part of my date(fIB) near the interface of process is calculated in another process . I want to access them and add them to the corresponding process. Any help would be much appreciated.
