Known bugs

location of grains

• In the location of grains table, if we chose it to be regular first, and then switch to random, nothing happened. In order to generate grains with random location, we need to remove the already added grains from the number of grains first, and keep the location of grains to be random, and re-add the grains.

• For Mac version of the software, we have some issues on pick up the structrue model. This bug will be solved soon.
