When i run the solver, it shows an error message:'Error: 7161 The mass matrix is zero' along with a warning: 'Not all domains are meshed'. The sizes are in nano domain. Model is attached for your kind reference. For meshing i used Mapped Meshing to reduce number of elements. I am using Version 3.5a on Pentium processor with 32 bit and 2 GB RAM. Thank You in advance Attachments: 4 terminal NEMS switch2.mph Reply | Reply with Quote | Send private message | Report Abuse Vahid Babakeshizadeh April 14, 2013 8:49pm UTC in response to Krishnachaitanya S Re: Error: 7161 The mass matrix is zero - resolve Hello Krishnachaitanya Don't leave the value of the "Electric Conductivity" as zero. Go to material section and edit the value for each material you have. Give it some small value at least 1. I'm sure it'll resolve your problem. Have fun.

INPUT: temperature gradient between thermo couple (Temperature) OUTPUT: voltage flow across thermo couple (Electric potential) I rectified all my errors. I changed "materials density and poison ratio value.." also but still it show "Error: the mass matrix is zero" I have attached the error image here.. Please help me to overcome this error.

For users of the COMSOL software package. – When I moved to the second step, COMSOL gave an Error message as follows: Error: 7161 … (Error:7161 The mass matrix is zero.). Unfortunately I still don't know how to solve it. Therefore, you can try the error 7161 first two methods first!
