Is there an example for custom load extension demonstrating APDL commands encapsulation on a multistep problem.?

    Here is an example.

    .xml file:

    <extension version="1" name="multiStep">
<guid shortid="multiStep">66F87991-B66E-425E-B2E6-D2C5C1DF31D9</guid>
  <script src="main.py" />
  <interface context="Mechanical">
    <images>images</images>
    <toolbar name="multiStep" caption="multiStep">
      <entry name="multiStep_Check" icon="Thermal">
        <callbacks>
          <onclick>createLoad</onclick>
        </callbacks>
      </entry>
    </toolbar>
  </interface>
  <simdata context="Mechanical">
    <load name="multiStep" version="1" caption="multiStep_Check" icon="Thermal" issupport="false" isload="true" color="#0000FF">
      <callbacks>
        <getcommands location="solve">writeLoad</getcommands>
      </callbacks>      
      <property name="Geometry"  caption= "Geometry" control="scoping">
        <attributes selection_filter="face" />
      </property>
    </load>
  </simdata>  
</extension>

    main.py file:

    def createLoad(currentAnalysis):
    load = currentAnalysis.CreateLoadObject("multiStep", "multiStep")


def writeLoad(load, solverData, stream):
    # Direct
    # if solverData.CurrentStep == 1:
    #     stream.Write("D, All, UZ,5" + "\n")
    # elif solverData.CurrentStep == 2:
    #     stream.Write("D, All, UZ,10" + "\n")

    ###########Using readlines#######
    #Scope only named selections##

    SourceDir = ExtAPI.ExtensionManager.CurrentExtension.InstallDir
    macFile1 = "step1.inp"
    macFile2 = "step2.inp"
    ns = load.Properties["Geometry"].Value.SolverName
    ExtAPI.Log.WriteMessage('2nd Method')
    if solverData.CurrentStep == 1:
        stream.Write("cmsel,s," + ns + "\n")
        fs1 = open(os.path.join(SourceDir, macFile1), "r")
        allLines1 = fs1.readlines()
        fs1.close()
        stream.Write("".join(allLines1))
    elif solverData.CurrentStep == 2:
        stream.Write("cmsel,s," + ns + "\n")
        fs2 = open(os.path.join(SourceDir, macFile2), "r")
        allLines2 = fs2.readlines()
        fs2.close()
        stream.Write("".join(allLines2))

    step1.inp:

    /solu
D, All, UZ,5
allsel,all

    step2.inp:

    /solu
DDELE,ALL,ALL
D, All, UZ,10
allsel,all
