Running the commands below, which are from https://www.openmodelica.org/doc/OpenModelicaUsersGuide/latest/ompython.html#enhanced-ompython-features, gives the shown error. {{{ >>> from OMPython import OMCSessionZMQ >>> omc = OMCSessionZMQ() 2020-03-12 15:58:29,708 - OMPython - INFO - OMC Server is up and running at file:////tmp/openmodelica.mwetter.port.b2a371262e6c4fb182a2e58d04ac0dee pid=49441 >>> model_path=omc.sendExpression(""getInstallationDirectoryPath()"") + ""/share/doc/omc/testmodels/"" >>> from OMPython import ModelicaSystem >>> mod=ModelicaSystem(model_path + ""BouncingBall.mo"",""BouncingBall"") 2020-03-12 15:59:14,981 - OMPython - INFO - OMC Server is up and running at file:////tmp/openmodelica.mwetter.port.f6bfd8fa2b0044b5a13ab273c9613b4c pid=49446 >>> mod.buildModel() Traceback (most recent call last): File """", line 1, in AttributeError: 'ModelicaSystem' object has no attribute 'buildModel' }}} Is such a functionality still supported? If not, is there a way to realize this in omc? I tried {{{ import shutil import os from OMPython import OMCSessionZMQ model=""Buildings.Controls.OBC.ASHRAE.G36_PR1.AHUs.SingleZone.VAV.SetPoints.Supply"" parameters=""(yHeaMax=0.7, yMin=0.3, TSupSetMax=303.15, TSupSetMin=289.15)"" omc = OMCSessionZMQ() omc.sendExpression(""loadModel(Buildings)"") omc.sendExpression(""simulate({}, startTime=0, stopTime=3600, simflags=\""-csvInput reference_input.csv\"", outputFormat=\""csv\"")"".format(model)) }}} with {{{reference_input.csv}}} {{{ time, uHea, uCoo, TZonSet, TZon, TOut, uFan 0, 1, 1, 293.15, 293.15, 283.15, 0 3600, 1, 1, 293.15, 293.15, 283.15, 0 }}} but {{{uHea}}} is always zero. Adding a terminating comma as proposed in https://openmodelica.org/forum/default-topic/2627-csvinput-usage-and-input-file-format#p8935 won't help. Moreover, I have not found a documentation for how to set parameters in the block {{{Supply}}}, hence the attempt with {{{ModelicaSystem}}} which appears to provide this functionality" defect reopened high Future OMPython v1.16.0-dev
