  1. Q Reactions are always correctly calculated but they can be wr…

    A
    1. inclined supports - only one component of the reaction is shown
    2. for supports close to the reinforcement. part of the reaction that goes into the reinforcement rod is not shown, but it will appear in the textual output in the node that belongs to the reinforcement and is close to the support condition.
    3. reaction at a joint which connects too regions will contain the reaction force only from one region and not the other. This may be especially a problem in case of load-displacement diagram monitoring. It is recommended not to monitor reaction or forces at geometrical joints that belong to more than one region. If it is neccessary then the reaction force should be monitored at all nodes with identical coordinates. The total reaction can be then obtained by their summation. 
  2. Q Sometimes, after lot of editing an error message appears.

    A

    In this case it is recommended to save your data and start the program again. In most cases this error does not result in any loss of data. 

  3. Q Some materials do not support Tangent predictor

    A

    Some materials do not support Tangent predictor. Elastic stiffness is used instead. This concerns the following material types: CC3DCementitious, CC3DNonLinCementitious where the tangent stiffness is supported only for cracking. CC3DBiLinearSteelVonMises, CC3DDruckerPragerPlasticity where the tangent stiffness is not supported at all. 

  4. Q Fixed crack model coefficient in 3D Cementitious materials.

    A

    The material models 3D Cementitious(CC3DCementitious) and 3D Non Linear Cementitious(CC3DNonLinearCementitious) exhibit unstable behavior when the material parameter "fixed crack model coefficient" (FIXED) is not equal to zero. Therefore it is currently recommended to use 0.0 for this parameter.  

  5. Q Nov. 3, 2001, Parameter k in Drucker-Prager model

    A

    The material parameter k for the Drucker-Prager material model is incorrectly generated and in addition the program wrongly requests this value to be negative. This problem will be fixed soon, but currently it can be only bypassed by manually editing the input file for the nonlinear analysis. The input file editing is activated if an appropriate check box is selected in the menu Options || Settings. 

  6. Q AnalysFS 실행 에러

    [해결방법]
    For current users of the NQA Version 3.0 or users of NQA Version 2.3.0, to do a complete installation using the two USB keys of the Version 2.3.0 (one for Baseline code and one for FS modules) please do the following:
        Step 1) Install from the ACSSASSINQAV3FS ftpsite, the Fast Solver and Standard Skyline Solver with Option A. During the installation uncheck the box for Baseline Skyline Solver. Make sure
    that you provide correct inputs for the DOS window at the end of the installation.
        Step 2) Install from the ACSSASSINQAV3BS ftpsite, the Baseline Standard Skyline Solver. Please let me know if you have any problem with the two-step installation using previous version USB protection keys.

    Please also make sure that all the INTEL redistribution package and Visual Studio 2012 files are also installed during the ACS SASSI installation.

    After installation you need to check that the configuration file .cfg is in the C:\ACSV300 installation directory and on the 2nd line has the correct RAM allocation in MB (16000 for 16GB RAM). You also need to check that the environment variables called MKL_PARDISO_OOC_CFG_FILE_NAME, MKL_PARDISO_OOC_CFG_PATH and SASSIPATH were defined during the installation. The MKL_PARDISO_OOC_CFG variable files are defined by the DOS program that opens a window at the end of installation (this software is called set_env4fs.exe and can be launched from the installation directory C:\ACSV300). The SASSIPATH is defined by the installer directly.

    Please also make sure that all the INTEL redistribution package and Visual Studio 2012 files are also installed during the ACS SASSI installation.  

     *** Please note that V3.0 needs the flag for saving restart files to be set on. ***
