Generally we perform sol 103 and sol 112 Modal Transient response analysis (nastran) acceleration data as input to find the response of structure eventually fatigue life of the component using ncode as fatigue solver .

Considering inputs as .op2 and .pch in ncode for fatigue solution .

Now I am performing modal dynamic transient response Analysis in abaqus considering the time-acceleration data (in amplitude ). In the output History i am requesting modal stresses (S) and modal participation factors GU, GPU .

Now i want to use the same FATIGUE SOLVER NCODE .but for the ncode to read the input file (.odb) must be converted to .guf file .for this ncode is recommending to use script namely odb2guf.pyc.

Can Any one provide me the script or help me out to solve the issue .

Any way to convert .odb to .pch file ?

Thanks &Regards
