![]() You have to play around with the import options in Comsol. This is reallly annoying and time-consuming to resolve. ![]() As Daniel suggested it is much easier to import the mesh into Comsol and then convert it back to a draw object in COmsol.ġ.) Errors in rendering the geometry. ![]() I am working on a very similar problem to yours - but using heart. 4.) My current experiments involving only one tissue at a time, but which would be the best way to create a geometry consisting of all the subdomains at one time? I mean skin, skull, brain (or WM+GM) and CSF together as different subdomains in geometry.Īhhh the pain of working with complex geometries in Comsol. Here is an example of used model of white matter in STL format - it seems to be good (MeshLab), what is wrong then, why I cannot create the mesh? 3.) Troubles segmenting the CSF. I have googled a lot, tried different settings while exporting to STL and then another different settings while importing in COMSOL, different settings of mesh - everything is useless, still I have such issues as: 1.) Errors in rendering the geometry. My workflow is following: MRI/CT data -> segmentation through Simpleware/Amira/SPM -> STL-file -> COMSOL. Some questions : I am trying to develop a quite simple, but realistic human head 3D model based on MR and CT images and use it as geometry in COMSOL Multiphysics. Simulations of an electrowetting lens (left) and molecular flow (right) using the Microfluidics Module.The pain of working with complex geometries in Comsol! Important applications include simulations of lab-on-a-chip devices, digital microfluidics, electrokinetic and magnetokinetic devices, inkjets, and vacuum systems. The Microfluidics Module brings easy-to-use tools for the study of microfluidic devices and rarefied gas flows. The Electrodeposition Module brings the power of COMSOL Multiphysics to electrochemical processes for such diverse applications as chrome plating in automotive industry, e-coating, electro-coloring, decorative electroplating, and electrodeposition for PCB manufacturing. The LiveLink interface is also bidirectional to allow you to initiate a change of the AutoCAD geometry from the COMSOL model. This means that settings applied to the geometry, like physics or mesh settings, are retained after subsequent synchronizations. The synchronized geometry in the COMSOL model stays associative with the geometry in AutoCAD. With the new LiveLink for AutoCAD interface you can transfer a 3D geometry from AutoCAD to COMSOL Multiphysics. Simulations of a retaining wall (left), a tunnel excavation (middle) and a flexible footing (right) using the Geomechanics Module The Module features tailored interfaces to study plasticity, deformation, and failure of soils and rocks, as well as their interaction with concrete and human-made structures. The Geomechanics Module is a specialized add-on to the Structural Mechanics Module for simulation of geotechnical applications such as tunnels, excavations, slope stability, and retaining structures. With this release, COMSOL continues to deliver on its promise to supply the science and engineering markets with the state-of-the-art simulation products for an expanding set of applications. Version 4.2 empowers current users to do more with their simulation environments, while new industries will now be able to leverage the innovation of multiphysics simulation. This is full retail version not academic or student version.you can use it forever have no time es only a dvd-r disk and all code needed,step by step installation instruction.World wide shipment,you will get it within 8 working days.ĬOMSOL Multiphysics 4.2 represents a significant expansion of the software's applications, features, and functionality.
