“We are really pleased to work with SimScale.”, said Michal Konicek from AccuCities. “Of course there are different ways to assess these requirements, but because SimScale is cloud-based, it is possible to assess a development in a wide city area without the need for an expensive hardware. Where speed of delivery is required, customers can even run multiple simulation scenarios in parallel.”
“These results show us a lot about accuracy, run time and our default assumptions.” says Darren Lynch, CFD Application Engineer at SimScale GmbH. “Firstly, the default value of 3 fluid passes is almost perfectly identical to 6 fluid passes, therefore, little evidence that running the additional time at a 100% additional run time cost will be worth while. Secondly, 3 passes is very similar to 2 passes, and therefore, if you are doing some early stage analysis you could run 2 passes at a cost reduction of 33%, but the user should be wary that they need to be looser in their analysis conclusions. Finally, it is observed that 1 fluid pass shows significant inaccuracies across most of the line, and should not be considered as a viable option despite reducing cost at a rate of 66% from the default value.”
