Calculation Times in 1.5.2 vs 1.6.2

Post by kpetek »

I recently upgraded from OpenSees 1.5.2 to v1.6.2 (cvs) and have noted significantly longer calculation times for the new version of the code. I made a simple 3D test model of a cube meshed with 1000 std brick elements. The ElasticIsotropic material was used and a single point load was applied over 10 calculation steps (Newton algorithm and BandGeneral solver was used because of interest for other models). Under version 1.5.2, this simple elastic model took 67 seconds on my machine. Under version 1.6.2, the model calculation took 477 seconds. The results and convergence behavior are identical for the two versions; however the calculation time is extremely different (7 times longer!).

Have others noticed the longer calculation times with v1.6.2 or have an idea why this is occurring?

:oops: Please disregard my earlier posting.

I had the compiler settings wrong in visual studio.NET and was compiling the debug version instead of the release version. The release version for 1.6.2 has similar calculation times to that of 1.5.2 for the example problem I referred to.

Sorry for the confusion. I hope others wont make the same mistake in the future.
