Some examples require external input files. Before you start, please follow the link in the Example Scripts section to download the zip file with model and result files.

Example 01 - Run HWC from Python

The example shows how HWC commands can be executed from Python using the evalHWC() method. The executed commands clean the session, load model and result files, and set up the session by modifying the page layout and copying the windows.

import os
import hw

scriptDir = os.path.abspath(os.path.dirname(__file__))
modelFile = os.path.join(scriptDir, "aerobox", "aerobox.fem")
resultFile = os.path.join(scriptDir, "aerobox", "aerobox-LC1-2.op2")

hw.evalHWC("delete session")
hw.evalHWC("hwd page current activewindow=1")
hw.evalHWC("hwd window type=HyperView")
hw.evalHWC("delete session")
hw.evalHWC("hwd window type = HyperView")
hw.evalHWC("open animation  modelandresult " + modelFile + " " + resultFile)
hw.evalHWC("view fit allframes = true")
hw.evalHWC("hwd page current layout = 9")
hw.evalHWC("hwd window copy")
hw.evalHWC("hwd window paste window = 2")
hw.evalHWC("hwd page current activewindow = 3")
hw.evalHWC("hwd window paste")
hw.evalHWC("hwd page current activewindow = 4")
hw.evalHWC("hwd window paste")
hw.evalHWC("hwd page copy")
hw.evalHWC("hwd page add title = Untitled")
hw.evalHWC("hwd page paste")
hw.evalHWC("hwd page overlay page = 2")

Example 02 - Export H3D into HTML

First, the example goes through the standard steps (setting up the window, loading the model/result files, and contouring the results). Next, it sets the animation frame and positions the model using HWC command.

This is followed by the main action - the creation of the ExportModelH3DinHTML object, setting up its attributes and calling the export() method to generated the HTML file containing the H3D results. Lastly, open_new_tab() method from the webbrowser module is used to open the HTML file in the default browser.

import hw
import hw.hv as hv
import os
import webbrowser

ALTAIR_HOME = os.path.abspath(os.environ['ALTAIR_HOME'])
modelFile   = os.path.join(ALTAIR_HOME,'demos','mv_hv_hg','animation','dyna','bumper','bumper_deck.key')
resultFile  = os.path.join(ALTAIR_HOME,'demos','mv_hv_hg','animation','dyna','bumper','d3plot')
htmlFile    = os.path.normpath(os.path.join(os.getcwd(),'H3D_to_HTML.html'))

ses = hw.Session()
ses.new()
win=ses.get(hw.Window)
win.type = 'animation'
win.addModelAndResult(modelFile, result=resultFile)

# Set scalar, vector and tensor results
res = ses.get(hv.Result)
resScalar = hv.ResultDefinitionScalar(dataType='Stress',
                  dataComponent='vonMises',
                  layer='Max')
res.plot(resScalar)

# Set time step
animTool=hw.AnimationTool()
animTool.currentFrame=res.getSimulationIds()[-2]

# Set View
hw.evalHWC('view orientation back')

print('Run ExportModelH3DinHTML() ...')
expModH3DtoHTML=hv.ExportModelH3DinHTML()
expModH3DtoHTML.file=htmlFile
expModH3DtoHTML.page=1
expModH3DtoHTML.winodw=1
expModH3DtoHTML.compressOutput=True
expModH3DtoHTML.compressionLoss=0.01
expModH3DtoHTML.animation=True
expModH3DtoHTML.includeSets=True
expModH3DtoHTML.includeMaskedElements=True
expModH3DtoHTML.results=True
expModH3DtoHTML.viewAttributes=True
expModH3DtoHTML.export()
print('Export to "{}" successfully finished!'.format(expModH3DtoHTML.file))

webbrowser.open_new_tab(expModH3DtoHTML.file)
