After I put down the phone, my heart never felt so heavy. I just called my parents in my hometown, Chengdu, a city with 12 million people, which is just 90 kilometers away from the center of the strong earthquake at a magnitude of 7.9. It has killed more than 10,000 people so far. The death toll is still rising hour by hour.

I am confused about apply BC of a model in abaqus. because I find that if I apply the accelaration of earthquake on BC, I must remove the fixed constraints applied on BC in previous step in abaqus. so the model become a free body without any constraints.
any expert can give me some detailed suggestions?thank you very much!^_^
In the attached paper (accepted for publication), we present enriched FE formulations to impose Bloch-periodic boundary conditions. Bloch-periodic BCs arise in the description of wave-like phenomena in periodic media: periodic composites, Schrodinger equation in quantum mechanics, photonic band-gap materials, etc. For a perspective, see the J-Club on elastodynamic bandgaps and metamaterials that was organized by Biswajit Banerjee
I am using Meshless Petrov-Galerkin Method(MLPG) for non-rectangular domains. There is a flexibility of using any shape for weight function and also for local quadrature domain. Here in my case case weight function domain and local quadrature domains are same.
I want to know that , for non-rectangular domains,how the different shapes of weight functions (specially circular or rectangular) will affect accuracy of the result ?
