Dual-permeability models are widely used to simulate preferential flow, but have not been incorporated into hydro-mechanical models. In this study, the COMSOL Multiphysics software was used to couple a dual-permeability model with a soil mechanics model for landslide stability evaluation on a ...
假设我们有一个瞬态模型,温度随时间波动。COMSOL 案例库中的硅晶片激光加热就是一个很好的示例。我们可以通过定义一个状态变量MaxT来追踪零件达到的最高温度,初始值为0(或任何低于或等于初始温度场的值),并使用此变量通过更新表达式存储最高温度: if(T>MaxT,T,MaxT) 无论何时何地,当温度场T大于MaxT时,此if...
如果您打算这么做,可以参考COMSOL Programming Reference Manual,因为您可能需要在删除之前知道每一行代码的功能。第二种方法更简单——直接在 COMSOL Multiphysics 的 GUI 中删除特征。将原始模型文件另存为一个新的文件,在新的文件中删除所有不希望出现在方法中的内容,包括几何序列、网格、研究步骤、可视化结果以及其他...
COMSOL Grab Bag: How to Use a Versatile CFD Code to Model Interesting Problems from Cryogenic Storage to Biofuel ProductionNelsonpres.pdf
In short, theCluster Sweepnode is a powerful tool that COMSOL Multiphysics supplies you with to help you be in full control of your modeling process. Note that to use a cluster sweep, a Floating Network License (FNL) is required. It is also recommended that you are familiar with the setti...
Concluding Thoughts on How to Inspect Your Mesh in COMSOL Multiphysics® We have discussed three different ways of inspecting a mesh, which can be used to spot regions with low-quality mesh elements. Now that we know how to find out where the low-quality mesh elements are, we can either...
Two objects, A and B, and the distances that we want to compute. We can compute all of these various distances using a combination of the General Extrusion and Minimum component couplings in COMSOL Multiphysics. Let’s first look at how to use the General Extrusion component coupling. We nam...
I am currently doing a project by working with Femlab/Comsol. There is a question I am stuck at: simulating the pump. DOES anyone knows how to approach this issue in Femlab or Comsol,like how to draw the geometry or which Module category I should use? At least any tips on how to app...
we can not remesh the deformed configuration. If we do select the check box, COMSOL Multiphysics will include nonlinear terms in the strain tensor. What if we have a problem with infinitesimal strains and do not want to include expensive and unnecessary nonlinear strains in the equilibrium equatio...
