ansys荷载工况组合 (转自新浪微博——majun的博客)

若用ANSYS进行设计，往往要计算很多种工况组合，如果加载能分开加载独立计算然后结果叠加（仅限于弹性阶段）则效率可提高不少，下面推荐几个命令即可达到这种效果。

The heat flow to the surroundings of an MLCC may take place by conduction,radiation and convection.It depends on the MLCC geometry,the thermal conductivities of the various materials (ceramic,terminations,solder,print boa

Abstract. We use a parallel direct solver based on the Schur complement method for solving large sparse linear systems arising from the finite element method. A domain decomposition of a problem is performed using a graph partitioning. It results in sparse

Abstract—In the framework of liberalized electricity markets, distributed generation and controllable demand have the oppor-tunity to participate in the real-time operation of transmission and distribution networks.This may be done by using the virtual power plant(VPP)concept,which consists of aggregating the capacity of many distributed energy resources(DER)in order

Abstract—This paper presents a load balancing method to improve network utilization when static routing algorithms are employed. Static routing algorithms can generally be reduced to a path assignment problem with the aim of minimizing a cost function: i.
