The following release notes are for the MiMiC v3.4.4 release.

The previous released version is v3.4.0. This version of the software is similar to v3.4.0, with these enhancements and corrected issues.

Product Enhancements by Application

New Modeling Block

• A new Simulation Studio modeling block has been added in this version.  The Matrix block is a data concentration of up to 400 floating point values.  The size is determined by the number of rows and columns defined for each Matrix block and ranges from 1 row and column up to 20 rows and 20 columns.  The block is found in the Modeling Blocks group.  The data is assigned, manipulated, and retrieved within a Calculation block expression.  New functions, specific to the Matrix block, have been added to the Calculation expression syntax.  For more information on the functions and the Matrix block, see the online help system. 

Custom Unit System

• User is notified of all uses of a custom unit when it is deleted from the simulation database.   If the user decides to continue with the deletion after notification, those blocks using that unit will be set to No Units.  Note that this change will require lock control of the Simulation Models containing blocks using the deleted custom unit. 

Testbench

• A new command, Question, has been added.  This command will allow the test script to prompt the user with a message defined in the script.  The prompt contains Yes, No and Quit buttons as well as an optional field to enter a note.  If the Testbench script is being logged, the button choice as well as the optional note is saved to the defined log file.

Backup Utility

• Addition of new command-line parameters /d <directory name> and /f <file name> have been added to backup utility.  These new parameters will allow the full path of the compressed backup file to be passed to the application.
• Use of the /S silent option without an argument will cause the currently active MiMiC database to be chosen. 

VIM Communications

• Enhanced DeviceNet and ProfiBus IO signal simulation to handle multiple signals sharing a register in various sizes.

Pressure-Flow Solver

• Enhanced error messaging for AMO blocks. t

Vessel

• Addition of heat exchanger inlet/outlet temperature reference points for use in other models. 

Furnace

• New parameters, Fuel_Burn_Fraction, Total_Energy_In, and Total_Energy_Out added to block.  These parameters are internally calculated for display and can be read via block reference or OPC. Enhancement of fuel handling with regard to nitrogen so that it is properly represented. 

L5K Tagbrowser

• Allows the processing of new (version 19) L5K ENCODED_DATA section to be safely skipped for encrypted Add-On Instructions.
   

Corrections and Optimizations in this Release

• SHX block used an incorrect heat transfer coefficient unit of W/m^2 °K instead of kW/m^2°K
• Memory leak fixed in Column View application
• Boiler AMO flue composition calculation continues if there is no fuel or air flow
• Storage of Foundation Fieldbus block channel data corrected to align with block list
• Source block properly saves data changed by the user while in online mode  
• PVnRT block snapshot restoration no longer adjusts vapor mass
• MiMiC Migrate utility updated to verify it conforms to the current database structure
• Boiler vapor generation calculations are no longer linked to the Ambient Temperature block reference configured for the object.  This could have prevented the vapor generation from occurring should the Ambient Temperature referenced value be higher than the starting temperature of the object. 
• Vessel outlet streams of mixed phase now correctly removing appropriate mass if Vessel is not using the VLE option.
• Separator TOTAL_MASS reference point incorrectly had a forced kmol unit applied instead of the kg unit
• Removed possible deadlock condition from Data View that could occur when examining DTB blocks 
• Conveyor handles restoration of a block with more segments than originally existed when snapshot was taken
• OTM service no longer fails to stop when requested by service manager
• DTB block initial values of DO_x will now be active when a model is first downloaded.
• VaporFlow block returns a flow of zero should both pressures become zero and no longer holds last flow value 
• PTCompensationBlock calculates the compensation factor correctly to appropriately “de-compensate” the value
• Valve object in a Pressure-Flow Solver model will correctly reflect passive node pressures
• Simulation Studio Save As function no longer leaves the source model Access Control locked on completion
• MiMiC Explorer IO Definition Initialization Item menus operate correctly for single or multi-select
• VIM Bridge node index no longer resets during access control lock acquisition failure.  Clears symptom of IO Ticker going bad followed by data for that VIM
• VIM Bridge Foundation Fieldbus dynamic data storage updated to prevent conflicts between other systems
• OPC Server no longer double-counts items added to more than one group

Updating / Installing the MiMiC v3.4.4 release

MiMiC users, current on MiMiC Software Support, can download the MiMiC v.3.4.4 software distribution from their software site license page on MYNAH.COM.  Click here to find out how to register for login to My Account at MYNAH.COM. The release is available as an MSI file. To install MiMiC v3.4.4, download and save the MSI file into a temporary folder, then double-click it from the Windows File Explorer. Add the update to the existing MiMiC folder by responding to the Installation Wizard prompts as seen below:

Step 1: Click Next.

Step 2: Select I Agree and then click Next.

Step 3: Browse to the existing MiMiC folder, then click Next.

Step 4: Finally, click Next.

Step 5A: The installer will remove the old version of MiMiC and copy the new MiMiC files to the installation folder.

Step 5B: If you encounter the error below removing MIMIC_DEFINES, contact Mynah support.

Step 6: MiMiC installation tasks will be performed.

Step 7: The “Get service credentials” step will display a dialog that allows you to choose which user MiMiC communication services should run as.  Choose the user for any service that requires special permissions.  Leave the user blank if no special permissions are required, or you are unsure.

Step 8: Installation is complete.
