【Python与Fluent的二次开发-TUI及Scheme代码】[Note 2]_pyfluent

---

前言

Python-Fluent coupled simulation：

Python equals to a client（客户端）, and Fluent equals to a server（服务器）, combined as a CS model.

---

一、Fluent配置环境

Enviroment Configuration

First define the working directory of the fluent. *Note the working directory should include the *.msh and *.py file.

Launch the Fluent as a server. FLUENT_AAS=1&OK

Then, the three .txt files are generated automatically in the working directory.

二、Python

1.import 库

ICoFluentUnit provide a set of functions: load and save case or data, set iterations, calculate and so on.

Python

import time
import pathlib
import os
import sys
import io
from fluent_corba import CORBA
import AAS_CORBA #import the AAS_CORBA module compiled from CoFluentUnit.idl

Matlab

orb=initialize_orb();
load_ansys_aas;
FluetnPath = 'Your own fluent work path';
aaS_Path = char(FluetnPath+"aaS_FluentId.txt");
 
ICoFluentUnit = actfluentserver(orb,aaS_Path);
iFluentTuiInterpreter = ICoFluentUnit.getSchemeControllerInstance();
 
ICoFluentUnit.loadCase('XX.cas');
iFluentTuiInterpreter.doMenuCommand('/display/mesh');
% 任务1、获取流体力
fileId = fopen(FluetnPath+"force.txt", 'r');
[force, count] = fscanf(fileId, '%f') ;
fclose(fileId);   
    
% 任务2、运动方程求解位移
[vel_n, dis_n] = calculate_y_motion(force(end), vel, dis);
dis_history = [dis_history,dis_n];
    
% 任务3、将位移传递到fluent中进行迭代求解
set_dis_commnd = strcat("(rpsetvar 'vel_n ", num2str(vel_n), ").");
iFluentTuiInterpreter.execScheme(set_dis_commnd)
