How to write an equation of gasket pressure variance for topology optimization response？
Hello,
I am trying to use OptiStruct to optimize the topology of a structure containing 3 gaskets. My optimization objective is the uniformity of gasket pressure, which is represented by variance (or standard deviation) of gasket pressure. So I created two responses, one is gasket pressure and the other is function. And then I want to write an equation for function to calculate the variance.
I wonder how to write the equation of gasket pressure variance?
Also I don't know what the response of gasket pressure refers to. Because the property selected for gasket pressure response actually contains a large number of nodes and elements. Obviously every node or element has its own pressure value. Is gasket pressure response a collection of pressure value?
Thank you
