HEC-RAS now has the capability to run the Linux compiled computation engines using Windows Subsystem for Linux (WSL). The WSL system and linux (e.g. Ubuntu) must be installed to use this new capability. Running Linux engines from within windows is intended testing and to assist preparing Monte-Carlo type runs on cloud services. The overhead initiating each WSL process makes simulations runtimes longer than native windows computation engines. This new option to use the Linux computation engines via WSL will only be visible if those files are installed with the special Linux installation package.
Under construction! More coming on this new capability in HEC-RAS 6.7 Beta 5.
