NewCaseListWithPhase(meshId, config, caseName=None, tags=[], priority='high', parentId=None, phaseCount=1)#

Submits a sequence of cases sharing the same meshId, where each case forks from the previous one. The maxPhysicalStep is split equally among the list of cases. This capability should only be used for conducting a long unsteady simulation to avoid running a single case for long time. For example, if the maxPhysicalStep is 1000 and phaseCount=2, the above API submits 2 cases with maxPhysicalStep=500 for each.

Parameters:

meshId (str) – Mesh Id of format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
config (path (str) or dict) – Flow360.json parameters for the case. It can be path to the json file or python dict.
caseName (str, optional) – Case name, if not provided it will be the same as config file name, required if dict provided as a config, by default None
tags (list, optional) – List of tags, by default []
priority (str, optional) – Queueing priority, ‘high’ or ‘low’, by default ‘high’
parentId (str, optional) – Parent case Id for forked cases. Format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, by default None
phaseCount (int, optional) – [description], by default 1

Returns:

List of case ids, where case id is of format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.

Return type:

str
