Hi all, 

     I am working on a transient study thermal VBA code. I have managed to get my code to switch from steady state to transient. however, I cannot get it to allow me to set a time step, total time, or to call in initial temperatures from a previous study. I will list my code below. Thanks for any assistance.

Set motionStudyMgr = Part.Extension.GetMotionStudyManager()
Set ActiveDocObj = COSMOSWORKSObj.ActiveDoc()
Set StudyManagerObj = ActiveDocObj.StudyManager()
StudyManagerObj.ActiveStudy = 0
'sets study name
NewStudyName = "Thermal 3"
Set CWNewStudy = StudyManagerObj.CreateNewStudy3(NewStudyName, 3, 0, ErrorCodeObj)

Set StudyObj = StudyManagerObj.GetStudy(0)
Set myModelView = Part.ActiveView
myModelView.FrameState = swWindowState_e.swWindowMaximized
Set ActiveDocObj = COSMOSWORKSObj.ActiveDoc()
Set StudyManagerObj = ActiveDocObj.StudyManager()
StudyManagerObj.ActiveStudy = 1

Set ThermalOptionsObj = StudyObj.ThermalStudyOptions()
ThermalOptionsObj.SolverType = 3
'ThermalOptionsObj.ThermalSolution = 0
ThermalOptionsObj.SolutionType = swsThermalSolutionType_e.swsThermalSolutionTypeTransient

               Two potential solution I found but cant get to work

                  'Option 1 
                     ' Total_Time = 100
                       ' Time_Step = 5
                        ' Step_Count = Total_Time / Time_Step

                  'Option 2 from solidworks
                        ' ThermalOptions.TotalTime = 3600
                          ' ThermalOptions.TimeIncrement = 600
