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.

High Energy Physics - Phenomenology Title: Non-diagonal charged lepton mass matrix and non-zero $θ_{13}$ Authors: J. Alberto Acosta, Alfredo Aranda, Manuel A. Buen-Abad, Alma D. Rojas (Submitted on 25 Jul 2012 (v1), last revised 13 Dec 2012 http://www.comsol.com/community/forums/general/thread/35432/ (this version, v2)) Abstract: Assuming that the neutrino mass matrix is diagonalized by the tribimaximal mixing matrix, we explore the textures for the charged lepton mass matrix that render an $U_{PMNS}$ lepton mixing matrix consistent with data. In particular we are interested in finding the textures with the maximum number of zeros. We explore the cases of https://arxiv.org/abs/1207.6093 real matrices with three and four zeros and find that only ten matrices with three zeros provide solutions in agreement with data. We present the successful Yukawa textures including the relative sizes of their non-zero entries as well as some new and interesting relations among the entries of these textures in terms of the charged lepton masses. We also show that these relations can be obtained directly from a parametrization of the charged lepton mixing matrix $U_l$. Comments: 16 pages, two figures. A parametrization of the mixing matrix $U_l$ was introduced to explain observed patterns in textures.
