Procast作为铸造仿真软件已经在铸造企业得到了广泛应用，尤其在航空航天领域。一个项目的模拟仿真过程往往需要几小时甚至几天，对于设计人员来说时刻盯着模拟计算过程实在无聊，所以开发一个小程序实时监控模拟过程，当模拟结束后及时通知设计人员，并记录完成时间和方案路径。
-
编程语言选用Python编写
-
Procast软件的模拟过程的调取，Procast的模拟计算开始后，会生一个***文件名.csv***文件，这个文件内容记录了步长，迭代时间，充型和凝固百分数等，我们项目一般凝固到100%即认为计算完成，所以可以采用监控此文件凝固百分数的办法获取模拟计算过程。

-
通知信息的发送，因为公司作为保密单位只有内网系统，内部使用飞秋通信较多。飞秋的通信协议代码如下
-
mystr = “1_lbt4_10#32899#002481627512#0#0#0:1289671407:模拟:通知:288:模拟完成”
# socket.AF_INET 网络通信，Windows AF_INET udp = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # SOCK_DGRAM表示UDP，SOCKET_STREAM表示TCP udp.connect((ip, 2425)) # connect函数的参数是一个元组，括号不能少(2425)是飞Q的端口号 udp.send(mystr.encode("gbk")) # 报文是以二进制的形式发送的 udp.close() -
程序UI界面采用Pyqt5编写，先在designer设计基本的UI界面。
后台逻辑通过eric软件将界面ui文件编译为python语言进行编写。
功能：当模拟开始后，点击OK打开项目地址中的csv文件开始监控模拟过程，模拟结束后自动通过飞秋发送给相关人员，并记录下项目信息，在文本框中显示。
