For my model I need an arbitrary mesh. Is there a program that I can use to create the mesh that I need and then load it in or is there a way I can do it within OpenSim?

Perhaps MeshLab (http://www.meshlab.net/) or Blender (https://www.blender.org/)? MeshLab was used in this student project: https://simtk-confluence.stanford.edu/d ... Downstroke.
