Re: CUP update

Yes, I can change the permissions. But this is abnormal to have to change permissions. Maybe it is the fault of the CUP update on COCO. Don't have the problem on the original install of COCOinstall_v3.5.0.0.

Re: CUP update

Same message. I had to reinstall the original COCOInstall_v3.5.0.0 and when it asked to update the CUP program, I declined. Able to run COCO with COCOInstall_v3.5 without the updates. I can update ChemSep. I tried updating COCO several time and always got the same message - "Windows cannot acce...

CUP update

COCO recently ran the CUP update and afterwards I get the following message when I click on the COCO shortcut or the executable file - "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."

Re: Not able to STOP simulation

I reran the simulation, then clicked on the STOP and waited. It took about 5 minutes before I got the User abort dialog box. So that function does work.

Not able to STOP simulation

I am using COCO version 3.2.03 and have recently encountered some issues. Some simulations that were previously saved under 2.7 are taking a lot longer to solve. When I try to stop the simulation by clicking on STOP, I do get the dialog box asking if I want to keep the results and I click on yes. Ho...

Controller solving issue

On the attached flowsheet I am heating an air stream and then humidifying with steam. When I change the Air heater exchanger outlet temperature, the controller C1 has trouble converging. I am using this controller C1 to make sure I have mostly condensate leaving the exchanger. Any recommendations?
