AI Thread Summary
Comsol Multiphysics can be used to solve a system of ordinary differential equations (ODEs), but it may not be the most efficient choice compared to specialized software like Matlab or Mathematica. Users suggest that if the problem aligns with existing application modes in COMSOL, it can be effectively addressed; otherwise, using PDE forms may be necessary. Additionally, there is a reported issue with COMSOL 3.4 installation, where users encounter errors related to missing class files and uninstallation failures. Guidance is sought on how to properly uninstall the program and the correct directory for the comsol.opts file. Overall, while COMSOL can handle ODEs, alternative software may be more suitable for such tasks.

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.
 
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
