求助一个有关Fortran动态链接库的问题

小剑

有一款仿真软件是使用如下方法进行二次开发的：
file:///C:\Users\XIAOJIANJJJ\Documents\Tencent Files\1429709479\Image\C2C\HTLG$2G3BL_EZRW)25~R4IJ.png1. Implement an equation for wear rate within the FORTRAN subroutine and save it as UserWearModel.fNote: A sample UserWearModel.f exists within the advanteng bin.
2. Compile the subroutine to a *.dll file by typing the following command into the Intel FORTRAN COMPILER:
>ifort /DLL /libs:static /threads UserWearModel.f
3. If necessary, rename the *.dll file as UserWearModel.dll
4. Replace any existing UserWearModel.dll file located in the advanteng bin with the new
UserWearModel.dll
5. Create a simulation

我按照这个用VS+IVF进行编译之后，替换掉原来的.dll文件之后，发现仿真软件无法正确使用了。还有就是软件自带的.dll文件只有8kb，而我编译的确有17.5kb，文件代码如下
c     User Defined Tool Wear Subroutine
c     Version 4.4-006
c     Copyright Third Wave Systems, Inc 2003
c     7900 West 78th Street - Suite 250
c     Edina, MN 55439
c     1.952.832.5515
c
      SUBROUTINE WEARMODEL_USER(wdot,pressure,velocity,temperature,
     1            uwearpar)
c
!DEC$ ATTRIBUTES DLLEXPORT :: WEARMODEL_USER
      implicit real*8 (a-h,o-z)
      real*8 uwearpar(10)
c
c uwearpar(10) is cutting velocity unless user assigns number.
c
c Usui's Model
c
      wdot=pressure*velocity*uwearpar(1)
     1     *exp(-uwearpar(2)/(temperature+273.15))
c
      return
      end

科研任务十分紧迫，我还是个新手，对动态链接库不是特别懂，希望有大佬指点！！！

替代了之后，没有错误提示，仿真软件直接点simulation,无任何反应，简单来说就是仿真软件无法正常工作了

我下载的 Dependency walker怎么打不开DLL文件

依赖项有这个msvcr90.dll文件是什么意思
