kandi X-RAY | vpic Summary

vpic is a C++ library typically used in Simulation applications. vpic has no bugs, it has no vulnerabilities and it has low support. However vpic has a Non-SPDX License. You can download it from GitHub.

VPIC is a general purpose particle-in-cell simulation code for modeling kinetic plasmas in one, two, or three spatial dimensions. It employs a second-order, explicit, leapfrog algorithm to update charged particle positions and velocities in order to solve the relativistic kinetic equation for each species in the plasma, along with a full Maxwell description for the electric and magnetic fields evolved via a second- order finite-difference-time-domain (FDTD) solve. The VPIC code has been optimized for modern computing architectures and uses Message Passing Interface (MPI) calls for multi-node application as well as data parallelism using threads. VPIC employs a variety of short-vector, single-instruction-multiple-data (SIMD) intrinsics for high performance and has been designed so that the data structures align with cache boundaries. The current feature set for VPIC includes a flexible input deck format capable of treating a wide variety of problems. These include: the ability to treat electromagnetic materials (scalar and tensor dielectric, conductivity, and diamagnetic material properties); multiple emission models, including user-configurable models; arbitrary, user-configurable boundary conditions for particles and fields; user- definable simulation units; a suite of "standard" diagnostics, as well as user-configurable diagnostics; a Monte-Carlo treatment of collisional processes capable of treating binary and unary collisions and secondary particle generation; and, flexible checkpoint-restart semantics enabling VPIC checkpoint files to be read as input for subsequent simulations. VPIC has a native I/O format that interfaces with the high-performance visualization software Ensight and Paraview. While the common use cases for VPIC employ low-order particles on rectilinear meshes, a framework exists to treat higher-order particles and curvilinear meshes, as well as more advanced field solvers.

            If Results is an array, what you need to do to create an array of the Make_Name property is to use array methods on the Results property. You have two ways to do this, given the above.

            Posting data to new row in Google Sheets (Python)
            Asked 2019-Mar-28 at 17:51

            So here's the problem that I'm facing. I've created a python script which takes the data from the first column of my Google Sheet, passes that into another API, gets the response, and then adds some fields from that response in the next columns of that row. The problem is that every time it updates the fields, it overwrites everything in the first row only and doesn't actually move to the second row.

            For example, if column A1 has the value x and that gets decoded into b,c,d. Then it writes b c d in columns B1, C1, and D1 respectively. That's all well and good. But when it moves onto A2, it writes the decoded values for that in B1, C1, and D1 as well instead of moving to B2, C2, D2. So it overwrites the last added values.

            ...

            ANSWER

            Answered 2019-Mar-28 at 17:51

            The problem is in the range parameter of your update() function call. In your code, the range is set to B:E in every iteration of the for loop, so it's always writing to the same 4 cells: B1:E1.

            Instead, you should increment the range by one row every time update() is called. Assuming you want to start writing in row 2: B2:E2, B3:E3, etc.

            Here's a working proof of concept based on your code, that reads the values from column A (range A2:A) and writes each value to columns B through E in the corresponding row:

            So it's been a long time since I coded. Recently got back into it and here's what I'm trying to do. I'm fetching VINS from a Google Spreadsheet and then using the Requests library to send a GET request to a URL which then decodes that VIN and returns the data (https://vpic.nhtsa.dot.gov/api/).

            Here's what I've done so far, I can fetch the VIN from the Spreadsheet and display it but when I try to send a GET request Python return a plethora of errors for me. This is the first time I've coded on Python and it's taken me some time to get the code to where it is now.
