What does the "testvalue" means in karamba

Hi. I hace been using Karamba for the past month to do some buckling simulations but there is one parameter that I dont know what is it for.
Because in the examples “testvalue” is always 0, but I have seen that if you increase that value the maximun displacement descreases considerably.
Is the “testvalue” relationed with the curing time of the concrete? what units does it have? and how its relationated with the young modulus and the yield strengh??
Thank you in advance :slightly_smiling_face:


Hi, the slider allows you to manually increase the youngs and shear modulus should you wish to alter this. You can see this in the expression and this allows you to increase the stiffness of the concrete
