Open a RFEM file, modify, safe the file under a new name and close it

[tobiasneulichedl]

Hi!
I am trying to open a RFEM file, modify some parameters like node coordinates, safe the file under a new name and close it.

Everything I want to do seems easy, except for the fact, that I can not open the file. My plan was to use the 'openFile' function.

openFile(r'C:\Users\Tobias\Documents\Github\RFEM_Python_Client\Gitterstuetze.rf6')
Model(False, "Gitterstuetze") # crete new model called Gitterstuetze
Model.clientModel.service.begin_modification() 

What do I need to change in order to open the file?

Hey @tobiasneulichedl,

I understood your issue. You are using openFile() function without setting prior connection to RFEM. To achieve connection with RFEM, you may use connectToServer() function or create dummay model by using Model(). Then after you can use function openFile() with model path and model name which return Model(False, 'model_name.rf6') and then you can start modification. In the end, you can save modified model using saveFile() with new model name and for model closing use closeModel('new_model_name.rf6'). Below you can find the sample code for this process.

from RFEM.initModel import Model, openFile, saveFile, connectToServer
from RFEM.BasicObjects.node import Node

connectToServer()         # or use 'Model()'

openFile('model_path/model_name.rf6')
Node(15, 15,0,0)
saveFile('model_path/new_model_name.rf6')
closeModel('new_model_name.rf6')

Let us know if it works for you or not.

Hi Heet!
Both suggested methods relative and absolute are not solving my issue.
Is there a chance we can have a look at the problem together?

[heetrojivadiya]

Hey @tobiasneulichedl, for better investigation, you may share code (create new branch and upload or just paste it here) or detailed snapshot.

[tobiasneulichedl]

I really just tried to run your example. Here the code:

`from RFEM.initModel import Model, openFile, saveFile, connectToServer, closeModel
from RFEM.BasicObjects.node import Node

connectToServer() # or use 'Model()'

openFile(r'Test.rf6')
Node(15, 15,0,0)
saveFile(r'Test_new.rf6')
closeModel(r'Test_new.rf6')`

Attached also the *.rf6 file.
Test.zip

And here is what I get:

Hey @tobiasneulichedl,

Thank you for sharing. I have corrected the file path. You can use any of the methods for assigning file path from below code.

import os
baseName = os.path.basename(__file__)
dirName = os.path.dirname(__file__)
print('basename:    ', baseName)
print('dirname:     ', dirName)
from RFEM.initModel import Model, openFile, saveFile, connectToServer, closeModel
from RFEM.BasicObjects.node import Node

connectToServer() # or use 'Model()'

openFile(dirName+'\Test.rf6')                                   # Method 1
Node(15, 15,0,0)
saveFile(r'C:\Users\RojivadivaH\Downloads\Test\Test_new.rf6')   # Method 2

Please make sure that you put your python file and .rf6 file in same root for method 1.

Let us know if it solves your problem or not.

[tobiasneulichedl]

Ok, now it works, thanks!

[tobiasneulichedl]

I have a followup question to this, since I am continuously struggling. Most of it due to my lack of python experience. But can you tell me whats not working in this code here:

import os
import pandas as pd
baseName = os.path.basename(__file__)
dirName = os.path.dirname(__file__)
print('basename:    ', baseName)
print('dirname:     ', dirName)
from RFEM.initModel import Model, openFile, saveFile, connectToServer, closeModel, Calculate_all
from RFEM.BasicObjects.node import Node

file_path = "namelist.xlsx"

df = pd.read_excel(file_path)

for index, row in df.iterrows():

    filename = row['name']

    connectToServer()

    openFile(dirName+filename)

    Calculate_all()

    saveFile(dirName+filename)
    closeModel(dirName+filename)

Run_rf6.zip

The goal would be to run a complete set of files, all after each other.

[heetrojivadiya]

I have checked and I found that the problem with file names. There are two times .rf6 in the filenames. Try to rename it and run again. It should work. Additionally, now you do not have to call connectToServer() with recent update in openFile() method in new merged PR #358.

[tobiasneulichedl]

Thank you!
