Discussion Overview

The discussion revolves around the use of Comsol Multiphysics for solving systems of ordinary differential equations (ODEs). Participants explore whether the software is suitable for this purpose and discuss installation issues related to Comsol.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Homework-related

Main Points Raised

  • One participant inquires about the capability of Comsol Multiphysics to solve a system of ODEs and seeks guidance on how to do so.
  • Another participant suggests that there are better-suited programs for solving systems of ODEs than Comsol, expressing uncertainty about its capabilities.
  • A different participant confirms that Comsol can be used for this purpose but recommends alternative software like Matlab or Mathematica unless the problem specifically requires Comsol. They mention the possibility of using PDE forms if applicable.
  • A separate issue is raised regarding installation problems with Comsol 3.4, including error messages and difficulties with uninstallation, prompting a request for assistance in resolving these technical issues.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the suitability of Comsol for solving systems of ODEs, with some suggesting alternatives while others affirm its capability. The installation issue remains unresolved, with no agreement on a solution provided.

Contextual Notes

Participants express varying levels of familiarity with Comsol, and there are unresolved technical details regarding the installation and uninstallation processes, including missing files and error messages.

Who May Find This Useful

Users of Comsol Multiphysics, individuals interested in solving systems of ODEs, and those experiencing installation issues with the software may find this discussion relevant.

Hi.

I need some help with Comsol Multiphysics. I want to know can I use this software to solve a system of ODEs only. If so, how can I do this.

Best regards.

Hi,

please can any help me. This is important.

Thanks,

bye.
 
I would say that there are better-suited programs to deal with systems of ODE's than COMSOL. I don't think its possible, but I'm not a COMSOL user.
 
Yes you can, but if your problem doesn't specifically require it would recommend something else like Matlab, Mathematica etc (shooting mosquitoes with a cannon like of a thing). If your problem fits some of the existing application modes then you can pick such, if not, use for example the PDE forms to formulate it.
 
Hello everybody
I have a problem with Comsol 3.4 installation, it doesn't run after the installation is finished.
I get the following COMSOL Error: "No class com/femlab/gui/Femlab on classpath."
I've tried to uninstall but also unsuccessful, I get the message:"EXIT FAILURE: Failed to load uninstallation components." and "Can't find comsol.opts file".
The question is whether there is a solution to uninstall the program and where the comsol.opts file has to be placed so it could be found during the uninstallation (I have the file but I don't know the directory where it should be placed)

I'll appreciate your help.
