coefficient of earth pressure at rest K0=0,5
Hello,

where I can type this coefficient in my model? I have an elastic Material but I couldnt find anywhere to write it in... I need it to see the stress sxx and syy and compare it to my analytic solution...
Here is a screenshot... I thought it must be here but no..

Hi,

There is currently no direct method to specify the K0 value. However, you can set the gradient of sxx​ and syy​ using either the X or Y variant. Tutorial 9, under the section Initialize the Stress Condition, provides guidance on this process. Additionally, you may find helpful insights in my discussions with other users on stress initialization here:

Another approach is to use a scripting language to loop through each element, extract the syy​ value, and assign sxx=K0? syy​ back to each element. Give it a try?start with a function, and I can assist you with refining it as you become more comfortable with scripting.
