how to add neo-hookean in model

Post by chen junnan »

Hi all

I am doing a simulation about the aortic dissection.At this stage, the simulation I made only uses Navier-Stokes and Nonlinear elasticity solver.And now I want to import the neo-hookean into my model.Do you know how to do it ? Can I do this in which part of the software? I have uploaded my sif document.Many thanks.

Thank you
best regards

ElmerModels Manual Page 61


Procedure File "ElasticSolve" "ElasticSolver"

Neo-Hookean Material = Logical True

By default the constitutive law (7.2) is employed. Switching to the neo-Hookean material model
(7.3) can be performed by giving the value True for this keyword.
