When I tried to do an analysis on a wood part, the Solidworks library did not contain enough wood data to do the simulation.  The message I received was: "The material in the default library can not be edited.  You must first copy the material to a custom library to edit it."  Apparently there is some custom library within SW that I can enter and install the wood properties of the wood I am interested in.  Once installed, I should be able to run my problem.  I have no idea how to access this so called "custom" library.  Can anyone help me access this custom library and use it?

Thanks.
