This means that the CONNECTION Client is not running or the user has not signed in. The CONNECTION Client that was installed with RAM Concept should be running and the user should be signed in to the CONNECTION Client. The user should also be already registered with Bentley Cloud Services. Currently, only one sign on session is allowed per user.

A problem with the environment or the application ID and/or cluster ID was encountered.

The program displays this error when manual tendons are detected within the optimization regions. The program gives an option to delete them or to keep them. Either way, the manual tendons will not be part of the optimization process.

The number of optimizable objects in a single region (or in the whole model) is zero. At least one optimizable object should be considered in one optimizable region.

The number of optimizable objects in a single region (or in the whole model) is over the maximum value of 75. Reduce the region size, reduce the number of optimizable objects or combine like objects into one. This limit has been used to avoid problems in the optimization to guarantee the finding of good solutions. The maximum recommended value to use in a region is 50.

The maximum number of iterations of 500 has been reached. Most models converge normally in less than 100 iterations. The program is having problems in finding a solution. An option would be to reduce the number of optimizable objects or use more optimizable regions to simplify the problem. This limit was set to avoid long optimization processes that may not have good results.

You cannot save and close the file if there are running optimization scenarios. If required, the user can run another instance of RAM Concept to continue working with another file.
