Why is the Young's Modulus and Poisson's Ratio missing for all the default materials in the material library?
This can sometimes happen if you have other products from the OpenFlows line installed.
First, go to Components > Engineering Libraries. Expand "Material Libraries", right click MaterialLibrary.xml and choose "remove". Once removed, right click "Material Libraries", choose "Add existing Library" and browse to:
This library includes the Young's Modulus and Poisson's Ratio for most materials. For those that do not, you will need to find and populate them yourself (from a reference manual for example). These values are only used in the Wave Speed Calculator tool.
