Dear sir,
I have analysed a shear wall building as per the sketch attached. The building is a symmetrical in x and z also in elevation. I used IS 1893 -2002 code and ESM and I find a lot of difference while checking the base shear calculated manually and compared the STAAD result.
I do not understand where I went wrong.
Somebody like Mr. Chris can help me to know better.
According to me deleting the existing surface and redoing is the only option where it is proposed to change the meshing size. If it occurs to somebody immediately after meshing that the size needs to be changed, then the undo option can be utilized.
I modeled the shear walls using surface elements and while modeling the element was meshed by the program itself. Now as suggested by Er.Sureshprsharma I tried to edit after selecting the surface element but I could not edit it to reduce the mesh numbers.
Anybody can help how to edit the surface element to reduce the mesh?

Mr. Rangarajan,
In my view 12 hrs is a very very long period. Either your PC may not be fast enough with the current configuration. Some virous problem may also be there.One more thing I am suspecting is that you must have considered default meshing of 10x10 in the shear wall or that may be still closer. Closely spaced nodes take unexpectedly higher time. Change meshing to 3x3 or 4x4 and see what happens. Please do not apply plates with meshing to simulate the floor slab.
Dear all,
As suggested by Er. Sureshprsharma I tried to model the shear wall-8No in my model for each floor thereby there comes to 160 shear walls. Having modeled I try to run but to my surprise and as I informed it took more than 12 hours and it went on and so I aborted. Can anybody suggest how to reduce the run time and start getting the analysis result and go to the next step for designing shear wall.

Mr.Sureshprsharma,
Thank very much.
