Hello everyone, I'm new in learning user defined model. I'm trying to compile the DEMOEX by using "Create User DLL",but when I follow the PSSE environment manager user guide to run "psseenvmanager_w.pyw" here comes a problem.

Traceback (most recent call last): File "C:\Python27\Lib\site-packages\psseenvmanager\psseenvmanagerw.pyw", line 6, in <module> import commonem as comonpy ImportError: DLL load failed:The specified module could not be found.

I wondering if "common_em" is a package of python, when check my "pip list" there exist common(0.1.2),it is the same thing?

import os
import sys
PSSE_PATH = r"C:\Program Files (x86)\PTI\PSSE34\PSSBIN"
sys.path.append(PSSE_PATH)
os.environ['PATH'] = os.environ['PATH'] + ';' + PSSE_PATH
import psspy

from psspy import _i
from psspy import _f

psspy.psseinit(100000)
psspy.case(r"""C:\Program Files (x86)\PTI\PSSE33\EXAMPLE\savnw.sav""")
psspy.fdns([0,0,0,1,1,0,99,0])

psspy.strt_2([0,1],r"""C:\Users\EE106\Desktop\try.out""")

could anyone can help me fix it? Very apperciate!! My PSSE version is 34.6.1

I prefer to use "create_dll.py". DLL creation works with the code below. Run it from a CMD window (not within PSSe GUI). Edit it to suit your case:

#candl.py
'''Create a UDM DLL.
It adds all *.flx, *.f,...,*.obj, *.lib files in working directory
to create a dll file.

default vars:
    keyname = 'dsusr'
    psseversion = 34

Open a "PSSe enabled" CMD window at your working folder,
    - To use with default parameters (edit lines 26-29 for updates), run it as:
        c:\..>python candl.py

    - To enter a dll name mymodel, run it as:
        c:\..>python candl.py mymodel
'''
import os, sys
import psse_env_manager
#__________________________________________________________________
def find_files(pattern,search_path=''):
    import glob
    """Given a search path, yield all files matching the pattern"""
    return glob.glob(os.path.join(search_path,pattern))
#______________________________________________________________
# [vars]
psseversion = 34
keyname = 'dsusr'
mypathlib = False  # set PATH and LIB values using installed components
src_lst = []                

work_dir= os.getcwd()
if len(sys.argv)>1:
   keyname = sys.argv[1]
dllname= "%s_%s.dll"%(keyname,psseversion)
dlllib = dllname.replace('.dll','.lib')
try: os.remove(dlllib)
except: pass

for ext in ['*.flx','*.f','*.for','*.f90']:       #include conec & conet files
    src_lst += find_files(ext,work_dir)           #get source files
objlibfiles  = find_files('*.obj',work_dir)
objlibfiles += find_files('*.lib',work_dir)

ierr = psse_env_manager.create_dll(psseversion, 
                                   src_lst, 
                                   modsources =[], 
                                   objlibfiles=objlibfiles, 
                                   dllname=dllname,
                                   workdir=work_dir, 
                                   showprg=True, 
                                   useivfvrsn ='latest', 
                                   shortname  = keyname,
                                   description='User Model', 
                                   majorversion=1, 
                                   minorversion=0, 
                                   buildversion=0, 
                                   companyname='',
                                   mypathlib=mypathlib)

Once the dll is created, load it with the python script performing the dynamic run, just before initialization, as:

import psspy
...
workdir = os.getcwd()
dllname= 'demoex.dll'
ierr = psspy.addmodellibrary(workdir + "\\" + dllname)          #load dll
...
psspy.strt(1,'outfile.out')            #initialization

Thanks your reply. Now I can use DEMOEX to create dll file by "create_dll.py",But when I try load dll into PSSE,it's show " Library not found (000301) " . how to fix it? thanks

try adding the full path for the dll file. If it does not help, show your script and your folder tree.

jconto (Aug 26 '1)

Sorry sir, I really new on writing it. Can I ask more detail about "adding the full path for dll file"? Is it adding in the "create_dll.py" or adding in the "DEMOEX.f" ? And where to add if the path should add in "create_dll.py"? Very appreciate of your help.

See my feedback on my answer above.

jconto (Aug 27 '1)
