Hi all, I have a drwing in .dxf format. its a 2d line sketch. The drawing has only 2d lines. It is basically the center line (through the wall) for the plan of a building. I wish to get the start and end coord of each line in this drwaing. i am using AutoCAD LT 2020. Is it possible to get this...
Hi, I need to built a 3d model using x,y,z coordinates..sample model prepared in a software is attached here.. the model might have 100nodes, of which not all coordinates are connected to each other.....I get the coorindates generated in my fortran95 program. I am using fortran tools6.1 which...
Hi, I am using fortran95 for writing a code.my doubt are:
1. Whether it is possible to autogenerate a variable. Ie; for i=1, the variable should be k1, then k2 and so on...
2. I have 2d arrays k1, k2, till k10 which are of nxn size...is it possible to have an array'k' which is 10 x 1 and can...
hi, i am analysing a simple frame structure - composed of a horizontal beam and a vertical column (the frame looks like '7' with 6 dofs restrained at the bottom of column)... i have prepared the stiffness matrix for the strcture, now need to prepare the force matrix..... i need to analyse the...
hi,
i have a generalised eigen value pblm,which is of form (A-λB)x=0... so i converted it to std eigen format, now the pblm is (B^-1.A-λ.I)y=0... how do i transform the eigen vectors of this std format to the eigen vectors of 'x'.
thanks.
Hi, i am trying to find the natural period of a vertical cantilever beam which is fixed at bottom and free at other end., i worked out the global M & K matrices and i have the eqn in the form [M]-w^2[K] = 0, the M & K are not diagonal matrices, but square symetric matrices of rank 6. i...
hi,
i know that principle stresses are the normal stresses acting on element when the element orientation is such that there is no shear stresses. as per text book, its nothing but the same normal stresses (in x,y) when the element rotattion is such that there is no shear stress on the element...
Hi,
Eqn 3.2.6 of dnv rp c202 states that the σho sd need not be taken if its positive (acting outwards of cylinder) while calculating the combined stress .. does this mean that the hoop pressure, if acting outward is not contributing to buckling ? please guide .screenshot attached frm code...
