sim command clears workspace & fails simulation

I am trying to run simulation using GUI. When I load my model, it shows me workspace is filled with variables, but as soon as sim command runs it clears all work space & simulation fails. I checked all the posts wrt this topic, but my issue is not solved. Can anybody please help me how to fix this problem ?

Thanks in advance. Sameer
