Hussam Ali Mohammed Modeling each brick with its proper dimensions and properties as 3D solid can only develop the reasonable structural analysis model. I found in different literature about modeling it as strut elements, or creating different scenarios of load only, wall only, wall in one plane -load in another plane, etc. but could not get a good way to model it. However, apart from being cumbersome and time-consuming, modeling it as a 3D solid is only the best way I thought.
I have not been following since last three years if there are new thoughts on this. Let me know if you have found/will find any.
