Hi all, My job is to simulate the practical testing procedures into software and check the results of the model before prototype. To do this we assign the physical properties of the material say YOUNG'S MODULUS, POISSON'S RATIO and DENSITY. Through these properties the software recognises the material and does the analysis as per boundary conditions given and loads applied. The above shown physical properties are assigned to model for different analysis. So, now my issue is: Is assigning DENSITY value to the model really necessay, when it is a STATIC ANALYSIS?
