我在https://software.intel.com/en-us/forums/intel-math-kernel-library/topic/720340的ABAQUS子例程中找到了一种调用MKL库的方法。我按照方法添加
compile_fortran=[...'/Qmkl:sequential'...]
它与degsv等常规MKL库一起很好地工作。但是当我要调用MKL-FFTW3库，ABAQUS显示错误，我检查日志文件，错误如下

Abaqus Error: Problem during linking - Abaqus/Standard User Subroutines.
This error may be due to a mismatch in the Abaqus user subroutine arguments.
These arguments sometimes change from release to release, so user subroutines used with a previous release of Abaqus
may need to be adjusted.
我使用了Visual Studio 2017，Intel Visual Fortran 2019，ABAQUS 2019。
感谢您的帮助。
所有这些FFTW3接口都集成到了英特尔MKL中。它们在英特尔®64体系结构的mkl_intel_ilp64.lib，mkl_intel_ilp64_dll.lib mkl_intel_lp64.lib，mkl_intel_lp64_dll.lib和mkl_rt.lib中定义。
您可以按照MKL Linker Adviser提示尝试与MKL手动链接。
