Hi everyone, I am doing a simulation using COMSOL 3.3a... I am using heat transfer module. I have 3 subdomains in my design with sizes in range mm, micrometre and nanometer....the third nanometre block appears just as a line...bt however i was able to give all boundary and subdomain details as i wanted....i did meshing and wen i proceeded with solving it says.... error 7147: out of memory in time dependent solver. how can i get through with this error.....please help me... Thanks in advance.
