Simple help in Meshing masonry

      Hi there!,


      Im using Ansys 15.0. Im new to Ansys and after trying for more then a day, getting a hexa mesh on my model i´m asking you for help. I attach a picture. I modelled the mortarlayer as one solid, where the bricks sit in. Even though im choosing hexdominant method i get these unfine elements. Especially on the upper surface of the structure. I would like to have a Hex-only mesh on the front surface that inflates by the thickness of the wall. can you please help me

      Hi Aniket,


      thank you very much. It didnt work for me the last time to add the picture to the post. Hope this time will work. 


      I got the Hexaeder mesh. It looks like (bricks hidden):


       



      And one picture of the bricks (mortar hidden):




      I have done tests on a masonry wall in the laboratory, in  which i introduced a moment to the wall until it failed due to opening of masonry joints. Basically a part of the wall was lifted up entirely including the ceiling. Now i wanna model the opening of the mortar joint in static structural. My first idea was to modell it with a material that fails, when one principal stress is in tension and with failing i mean that stresses in this element will fall to zero (Maybe killing the element?). But I failed finding the appropriate material in engineering data. Is static structural capaple of deleting elements when principle stress is in tension? I have´t heard anything about fracture mechanics yet and i try to bypass it, since i have limited time to submit my results. I send you a picture of the wall (past the tests), where failure gaps are highlighted.


      Regards and thanks for help

      We applied a load to the steelbar which equal a moment to the wall.
