Hi In my problem, I run many simulations for which I just multiply each element's stiffness matrix with a scalar. I use linear elements and the stiffness matrix is always the same. I just need to multiply it with a scalar.
I'm using the FEMSystem class, following the example given in http://users.ices.utexas.edu/~roystgnr/libmeshdoc/fem_system_ex2.php, (btw the link in the github website is not working, http://libmesh.github.io/examples/fem_system_ex2.html) How could I just calculate the stiffness matrix in one quadrangular linear element and reuse it in the remaining elements? I've tried adding a flag inside of the element_time_derivative() routine. Doing so I can save time building the stiffness matrix, but the code still wastes time calculating all the shape functions in advance. I've tried finding where they are calculated without success (I'm not good at debugging yet) Thanks in advance Miguel -- *Miguel Angel Salazar de Troya* Graduate Research Assistant Department of Mechanical Science and Engineering University of Illinois at Urbana-Champaign (217) 550-2360 [email protected] ------------------------------------------------------------------------------ BPM Camp - Free Virtual Workshop May 6th at 10am PDT/1PM EDT Develop your own process in accordance with the BPMN 2 standard Learn Process modeling best practices with Bonita BPM through live exercises http://www.bonitasoft.com/be-part-of-it/events/bpm-camp-virtual- event?utm_ source=Sourceforge_BPM_Camp_5_6_15&utm_medium=email&utm_campaign=VA_SF _______________________________________________ Libmesh-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-users
