Good morning. We are looking forward to this fix. we've been working on the dynamic script for a month and it's a series of failures. when the sensor recognition function works, the simulation does not work based on it. Please go back to live view! Or at least the possibility of input based on Excel, CSV in the corrected version of Dynamic Script. I'm counting on you! :-)

Good morning, I am continually encountering issues with mastering integration based on "dynamic scripts". I have modified the virtual sensor creator file, taking into account the unique mine ID number in the VSLOCATION column... I kindly request that you look into this problem. As I suggested in an earlier post, I believe it would be beneficial to allow descriptions and definitions of columns and data that are inputted into Dynamic Scripts. Currently, if I have different input data from my system, it doesn't work because the date and time format is different from that in Ventsim. I think such a feature, as was previously available in LiveView, worked very well and allowed me to integrate various types of data from different sources in the program. I am counting on your support. Yours sincerely, Andrzej Szmuk

Good morning. Thank you for the quick reply. I understand. Can you expand (return) to the possibility of free data mapping (Data source, Column name mapping - schema) in the next update, as it was in previous versions of the program. It was a very helpful solution. .... Can Ventsim control work as a virtual machine or does it have to be in the form described on the website (Dispatch room). We already have such a system in the mine. a change of supervision would be very costly. Maybe you can make VentSim Control available for users, eg for a limited number of sensors. Please consider it again. Sincerely, Szmuk Andrzej

Good morning. I kindly ask for help regarding connecting my model with the network of telemetry sensors at the bottom of the mine. The updated version of the program lacks the ability to connect with VentSim Connect as described in the manual. I've been using the program for years and there used to be a possibility to integrate data from different files along with assigning values, descriptions, sensor types in various columns. It was possible to define which column in the file corresponds to a given range of data. Now there is no such possibility, or I simply can't find it. Currently, I have one data formats from the telemetry system: I. IDENT# CZAS POMIAR TypCzujnika JEDN# LOKALIZACJA X Y Z ZX:001 2021-03-01 10:13:39 1 Control unit Oil chamber pos.705 ZX:004 2021-03-01 10:13:39 1 Control unit Conveyor cut DF pos.1080 The files are being overwritten. However, the ideal solution would be to freely define data columns - because systems vary. I kindly ask for your assistance. The matter is urgent for me. Best regards, Andrzej Szmuk (JSW S.A.)

I forgot to add that I have version 5.4.2.0 and I'm not sure that these problems have been fixed in newer versions ...

Good day. I check the "piston effect" in 1000 ways ;-) The program lacks: 1. During dynamic simulation, it does not show the pressures related to the piston effect. 2. Inability to generate charts from "DYNAMIC MONITOR" 3. Is it possible to graphically show moving vehicles better? 4. "Pressure Total Relative" does not change in dynamic simulation. And it is very important. Because you could read the pressures in front of and behind the vehicle. Please, analyze the possibility of introducing the above comments. I believe this will contribute to the development of the program. ;-) Sincerely, Szmuk Andrzej

Good day. I have a problem with "piston effect" in simulation. The train runs in th e tunnel at a speed of 100 km / h every 4 minutes. The results for air velocity and air volume seem correct. I have a problem with the pressures. They are very small. Please explain how the "piston effect" is calculated? am I making a mistake somewhere? Enclosed are photos with the results ... I am asking for a quick reply. Sincerely, Szmuk Andrzej

I ask you to try in new versions of the program to introduce outposts (security through employees so that they do not reach the danger zone). Assumptions - an employee who ensures that someone does not enter the fumes must stand in: stabilized clean (fresh") air at least after a double collapse of the excavations (in case of explosion). The second idea is to introduce zones and dams (dust, water) to prevent the transmission of carbon dust explosions. In the case of an explosion simulation (an explosion of coal dust or methane could be introduced) - then the explosion would not be pointy only would move up to the dam - where the flame and further spread would be interrupted - only heat, gases ... and in the case of an inflammation or explosion of methane - the explosion force would take into account the amount and concentration at a given mine site. Ideally, an automatic explosion would be taken into account in places with methane or the spread of coal dust. I also miss the assessment of the possibility of fire gases or secondary fire outbreaks at intersections with "fresh" air currentsWhat do you think? With respect, Szmuk Andrzej

Good morning. Is it possible to model airflow (with automatic, preliminary determination of aerodynamic resistances). I manage to create objects from the point cloud in the form of dxf, and I would like it to be a ventilation route. please help. With respect, Szmuk Andrzej

Good day. We are at the beginning of the PumpSim learning journey. After entering part of the network, an error pops up as in the picture. What could be the reason? Please help.

Good day. We noticed in the company that during the FireSim or MuliSim simulation - heat simulation does not work in the ducts. We want to observe the operation of the cooler during the FireSim simulation. Maybe we're doing something wrong? Please help. Regards. I have VnetSim v.5.4

Good day. I noticed in the VentSim version 5.4 program that when I add linear methane emission to the excavation, the program calculates it incorrectly (in the older version it was correct). The problem also appears when the option of linear emission is selected (with the option "dry air gas balanced" not selected. I suggest in the future to enable methane emission in one unit, e.g. 10 m3 100% CH4 / s. Converting emissions into 100 m of excavation is troublesome. Maybe I am wrong ... I will go for help.
