License Error -18

Hi
I am using COMSOL to simulate the current change with diffusion of reacting species in transient state. I can do the calculation in version 3.5a, but not in version 4.1. The Transport of Diluted Species and Electric Currents module were used. The error message appears right after the compute command was choosing. The error message was :

Error in automatic sequence generation.
Could not obtain license for AC/DC module.
License error:-18
License server system does not support this feature.

I can use exactly the same module to simulate the problem in stationary state. The problem only appear while I am trying to calculate the problem in transient state.

I would be appreciated if someone can tell me what the problem is.

Thank you,

Jo

Hi

I suspect you have some combination of modules required and that you do not have all, with v4.1 the mix of physics and applications need are crossed. Check it out with your local comsol rep

Good luck

Hi,
After the insallation, an error message appears"License server system does not support this feature". I do not know how to solve this problem?Could you please tell me how to solve this issue to lmake the program working? Or you can tell me the detailed installation procedure of Comsol 4.1. Actually I get bored from installation many times, and still face the same problem.Thanks.
