Hi,

I want to model elasticity and have a given young's modulus. I have added springs to my model as discrete elements and want to translate the elastic modulus to the spring constant. I have chosen several nodes where I have applied the springs and then assigned the material "MAT_SPRING_ELASTIC" but the problem is that it is the spring constant  [N/m] that is used in that material and not the elastic modulus [Pa] which is the only material parameter that is known in my case.

spring constant or stiffness is  K=AE/L

A= area

E=youngs modulus

L=length
