Merging mesh problem

[Mechanicslearner]

Hi I tried to mesh these two plates with two cases having different geometries. I am trying to achieve something similar in complex geometry in abaqus. But I think the problem is with shapes or if it is something else, please help me with this. I tried in solid elements too it did not work either. I have attached image where you can see two cases

Hi muralimanoj

the reason why the nodes in case a) are not being merged is becaus they are otuside the tolerance. As you can easily see in case b) every node of the fine mesh is coincident with a node in the coarse mesh. This is not the case in case a). If the fine elements are exactly half the size of the coarse elements it should work.

Hi Ruham,

Thank you very much for solving my problem and help to increase computational speed. Is there anyother way than adjusting tolerence in merge mesh to match nodes of other part so I would get close to perfect triangular element shape?
