Good Evening all,
Me and my team have been perfecting this geometry from a year, and have finally arrived at this model for a steam generator (SG).
The SG is a straight shell and tube type heat exchanger, where water enters into the SG via the central inlet and exits out as steam.
The water stream is pressurised to 80bars. The water is heated through natural convection with the help of lead.
While, the appropriate physics have been added, while trying to simulate it with stationary, and time-dependant studies, our workstation runs out of memory due to the high number of DOFs that are being created even at the coarsest level.
Kindly help us regarding this, on how to simplify this model, or simulate this. We need the heat transfer and fluid profiles for this SG.
The file for this SG model has been attached below:
the mph file is 29MB even with the physics removed (it was 1.9GB with the physics and extra-coarse mesh) ...... what do I do?

To make the file that you want to post smaller in size, consider doing these operations on it: Study --> Clear All Solutions . Mesh --> Clear All Built Meshes . File --> Compact History . Then save it with a new file name and check how big your file is. See also: https://www.comsol.com/support/learning-center/article/how-to-reduce-the-size-of-your-model-file-48201
