That error you mention is not an error it is just a warning - also it is a fine warning, since only sets a keyopt(6)=1 I believe, so it does not involve units, hence we can neglect that warning, and it should be all OK and have run through till the end. So under Solution there are only warning and no errors in your model most likely (errors prevent the solution to finish, warning do not and we need to assess if they are important or not, like in this case it is not).

Can you please show us the model after it has been solved as an inline image, and all the warnings under the solution and messages - thank you.
