[M. Rojas]

Hello everyone.

I need help, I'm a new user with Ansys, I installed the program a month ago, for my class I created different simulations, and at that time the simulations were working fine, but recently Ansys doesn't work, I've been looking for solutions but I don't know now the program shows me a problem with a memory, I didn't install other programs after installing Ansys, can anyone help me? Attached a solution information.

Hi M. Rojas,

It looks like that the error is associated with the memory size available in your computer. You can increase the memory of your computer and if this is not possible, you can simplify the model. For example, you can use shell elements instead of solid elements, or you can use larger element sizes to mesh your model. Also, try varying the mesh density to have small elements only in critical regions.

I am also facing the same issue. I was searching for https://casinosanalyzer.com/online-casinos/jackpotmolly.com website online because I want to read Jackpot Molly casino site reviews and over there I easily found it with amazing bonus and free spin offers. While searching for it online, I found a link to your post.

Finding great mobile app developers is not easy, but I have a great site that can help you a lot. I'm a budding businessman, I have my own online store, but I didn't even know where to start. Yii2 framework - helped me in this, the result exceeded all my expectations. They have many projects, all you have to do is go to their website node js websites and see for yourself.
