[Simvascular-news] simvascular on linux

Dear all, I am quite new to linux, and I encountered a problem with simvascular. After I installed simvascular on Ubuntu 15.0 and ran a example, I just god a error message: "/usr/local/package/simvascular/1439887281/flowsolver-bin.exe: error while loading shared libraries: libmpich.so.10: cannot open shared object file: No such file or directory" I have tried $sudo apt-get install mpich2, but it didn't work. Do you know how to solve it? Thank you very much! Best regards, Zihan
