Hello community, I want to simulate the CO2 capture process using MEA. I already achieved this in Aspen Plus, since this simulator has suitable thermodynamic packages (E-NRTL, Amine, etc.). The results I get are in line with literature values. On the other hand, DWSIM does not have those thermodynamic packages and therefore does not include the reactions involved in the absorption and desorption of CO2. I have seen several forums where people upload simulations in DWSIM, indicating that they cannot...

That was it. It solved the error. I will have to run the program as administrator, but at least I can use it. Thank you, Daniel, both for the development of DWSIM and for helping me to solve this issue. Warm regards

Hi Daniel, Thank you for the fast response. The option "Enable CPU SIMD acceleration" in General setting is not active (default settings) I tried by selecting and deselecting it but the error keeps showing. Any other suggestion?

Dear Community, Firstly, if Daniel gets to read this message, I want to thank him for the development of the DWSIM simulator, without a doubt the best open-source process simulator in the market. Returning to my problem, the aforementioned error under consideration appears after pressing the button “Solve Flowsheet". The flowsheet can not be solved, not even a simple stream. The error appeared when I installed DWSIM version 7.3.1. I then decided to reset completely my computer (Windows 10) and install...
