We live in the day of automatic<\/em>.\nIt seems like every day there is a new task that can be handled automatically.\nSmart thermostats make sure the house is comfortable when returning from work.\nHome lighting themes customize an ambiance based on who is home and the time of\nday. Automatic delivery of your household goods ensures you\u2019re never out of\ntoothpaste. The automatic\npotato peeler<\/a> saves you from having to peel potatoes by hand\u2026ok, well maybe\nthat\u2019s going too far. The point is that technology is great for taking care of\ntasks based on rules or schedules so that you can focus on more important\nthings.<\/p>\n\n\n\n

The pervasiveness of automation makes it even more annoying\nif once you get to work and sit down to run a simulation, you need to fine-tune\nsettings and fiddle with parameters. Or, even worse, if it\u2019s necessary to babysit<\/em>\na challenging case to make sure it runs as expected. Now, there likely was a\ntime in your professional life when diving head-first into the details of flow\nsolvers was interesting and, dare I say, fun. I know it was for me and if\nyou\u2019re reading this blog, then I bet it was for you too \ud83d\ude0a. In fact, when it\u2019s\npossible to set aside time to dig into some new and different case, it\u2019s still\nfun to research the best methods to use and how to apply them.<\/p>\n\n\n\n

Daily work is different, though. Timelines are always shorter. More data is always needed. Your attention is always split between half-a-dozen urgent tasks, not to mention the ever-growing list of work that you keep meaning to get to once you have time. Forget tuning simulation methods for each case, you need to set up the case once knowing that it will run quickly, reliably and give accurate answers.<\/p>\n\n\n\n

Simcenter STAR-CCM+ 2020.1<\/a> has that need squarely in mind. Among the many capabilities that this release brings, one that I\u2019m most excited about is the automatic coupled solver control. The coupled solver is the go-to solver for flow and heat transfer analysis for many application areas, including my focus area of turbomachinery. The solver provides extremely accurate results and is great for very large grids, which are often needed for high-fidelity flow and heat transfer analysis of complex turbine blades. However, large and complex cases often required prior knowledge and expertise to achieve fast convergence.<\/p>\n\n\n\n

\"Gas<\/figure><\/div>\n\n\n\n

The coupled solver received two sets of improvements that\nwork together to dramatically improve workflow and turnaround time for both the\ncases that need to run automatically out of the box and the cases where you\nwant specific control of settings: a reorganization of settings and an\nautomatic solver control method. <\/p>\n\n\n\n

Simplified Setup<\/h4>\n\n\n\n

The organization and presentation of solver settings has\nbeen dramatically simplified so that it\u2019s much easier to apply settings. As an example,\ncheck the comparison below on how the setup of the \u201cExpert Driver\u201d option has\nbeen simplified.<\/p>\n\n\n\n
