Stress assist mass diffusion analysis

Stress assist mass diffusion analysis

Stress assist mass diffusion analysis

(OP)
Stress assist Mass diffusion analysis.

     To understand, i tried to work out the example problem 8.1.2 in Abaqus example problem manual "Stress analysis with linear elements, followed by a mass diffusion analysis with linear elements".
      Initially i did the stress analysis by taking the input file from example  " difftocrack_linearstress.inp" and wrote the results to use in mass diffusion analysis in"difftocrack_linearstress.odb" .
      Case1:Then i tried to do the stress assist Mass diffusion analysis by taking the example input file "difftocrack_linearmassdiff2.inp" and by defining the predefined field in initial step , category: Mechanical, types for selected step: stresses (step-1, increment 1) from the output database file of stress analysis "difftocrack_linearstress.odb".
      Case 2: Then i also tried to do the stress assist Mass diffusion analysis by direct specification of stress predefined field.
    For both the case i am getting an error msg : "Analysis input file processor exited with an error".
