Set initial values in Global Equations ODEs

Please login with a confirmed email address before reporting spam

Hi,

I am new to Comsol 4.3. I used "transport of diluted species' to solve the concentration profile. Then I want to use boundary ODEs to solve several ODEs. For one of the ODEs, the initial value is the result of the concentration profile in the previous study. How I can possible input the previous solution in the initial value (u_0); field. Any comment will be appreciated.

Thanks

Hi,
this bug related to opening files of future versions was fixed in version 4.3. The new release is being sent out now and some territories have not received it yet.

If you are in urgent need of the new version, please contact your COMSOL sales representative.

kind regards
Niklas

Hi Niklas

Good to hear, then it's probably in the post somewhere on its way :)
