NeoHookean Stored Energy Function in output file

[tseeriksson]

Hello!

Just a general question, I'm using FEAP 8.3 and I use my own material model for a nearly incompressible nonlinear material. In the input file I specify:

Material 1
Solid
Finite
Mixed
Ucons ....

Whenever I use finite in the input file, in the output file, FEAP always puts

M e c h a n i c a l   P r o p e r t i e s

     NeoHookean Stored Energy Function

          3-Dimensional Analysis

          Modulus E        1.00000E+00
          Poisson ratio    0.00000
          Bulk Modulus     3.33333E-01
          Shear Modulus    5.00000E-01

From what I can tell, this doesn't actually affect the solution, but I just wanted to make sure.
Does it have an effect on the simulation? Why is it there?

Thank you!

This is a bug.  Check the input module in /elements/material (inmate.f) .  There should be a reset of 'imat' just after the check:  elseif(pcomp(text(1),'ucon', .....

    imat = 0
    umat = 0

This should prevent the print.

Great to hear it was only a bug!
 
Adding imat = 0 prevented the printout.

Thank you!

This is a BUG -- we have corrected for future releases.  Thanks for pointing it out.
