This page describes how to fix a bug in the dll of EnergyPlus 7.0.0, build36 that may occur when exchanging a large amount of data in each time step. The error message that EnergyPlus writes to its .err file is

 ExternalInterface starts first data exchange.
 Error: No digits were found in getDoubleCheckError.
 Further characters after number: 
 Sending EXIT_FAILURE = : 1
 **FATAL:Error in ExternalInterface: Check EnergyPlus *.err file.

To fix the bug, proceed as follows:

Windows

  1. Install the BCVTB version 1.1.0
  2. Copy the file bcvtb/lib/util/bcvtb.dll, where bcvtb is the top-level directory of the BCVTB installation, to the EnergyPlus directory, such as C:\Program Files\EnergyPlus-7-0-0. This will replace the existing file with the same name.

Linux

  1. Install the BCVTB version 1.1.0
  2. Copy the file bcvtb/lib/util/libbcvtb.so, where bcvtb is the top-level directory of the BCVTB installation, such as /usr/local/EnergyPlus-7-0-0. This will replace the existing file with the same name.
