Mesh element

      I have a problem to understand how ansys workbench generate number of element after providing mesh size element?


      If i have a model of 1m X 1m X 1m (length X breathX height) and i provide element size as 0.5m then my total number of element for model is 8. may be i am wrong.


      I have a model of 3mX2mX0.3m ( length X height X width) if i provide  0.3m element size on that model (explict Dynamic).  My problem is how it will divide my model to provide number of element? specially from height part


      if we have a calculation


      2/0.3 we get 6.66.


      Do we have other method to apply mesh size to remove error?


      Waiting for your response.


      Thank you

      You'll not get part elements, the meshing tool will adjust the cell size to fit into the domain with full cells. What error are you seeing/worried about?

      Thank you for your help. 


      I was worry about part elements and now i understand I  got error because of large element size.  in above case can we consider our element size is  0.3m for all elements?


      Thank you.

      Have a look at the hard and soft size settings. In terms of cell size, we also look at mesh resolution: do you have enough cells to calculate the stress/strain/bendiness etc you're going to observe? You could use 0.3m sizing giving 10 x 7 x 1 cells but it may not be sufficiently resolved.
