I am thinking about how can we import complex .txt file (Ansys/Abaqus) to MMA for the selected database? For example: **txt file (input file)**: ... ... 10894, 10895, 10896, 10897, 10898, 10899, 10900, 10901, 10902, 10903, 10904, 10905, 10906, 10907, 10908, 10909 10910, 10911, 10912, 10913, 10914, 10915, 10916, 10917, 10918, 10919, 10920, 10921, 10922, 10923, 10924, 10925 10926, 10927 *Edfsf, cadifd=Saoot-23, coming 10122, 10534, 1 *Gaaf, nlau=Saoot-24 29, 30, 31, 32, 33, 34, 400, 401, 402, 403, 404, 405, 406, 407, 408, 409 410, 411, 412, 413, 414, 415, 416, 439, 440, 441, 442, 443, 444, 445, 446, 447 3157, 3158, 3159, 3160, 3161, 3162, 3163, 3164, 3165, 3166, 3167, 3168, 3169, 3170, 3171, 3172 3173, 3174, 3175, 3176, 3177, 3178 *Edfsf, cadifd=Saoot-24, coming 1477, 1782, 1 *Gaaf, nlau=Saoot-25 32, 33, 76, 86, 455, 456, 457, 458, 459, 460, 461, 462, 463, 464, 465, 466 9611, 9612, 9613, 9614, 9615, 9616, 9617, 9618, 9619, 9620, 9621, 9622, 9623, 9624, 9625, 9626 9627, 9628, 9629, 9630 *Edfsf, cadifd=Saoot-25, coming 8891, 9060, 1 *Gaaf, nlau=Saoot-26 24, 25, 28, 29, 30, 344, 345, 346, 347, 348, 349, 350, 351, 352, 353, 354 355, 356, 387, 388, 389, 390, 391, 392, 393, 394, 395, 396, 397, 398, 399, 400 ... ... What do we need is the **output in MMA (matrix)**: 10122 10534 23 1477 1782 24 8891 9060 25 Import rule is: we find ***Edfsf** line: the value after the key words **Saoot-** and the following line two values: namely **10122 10534 23** then we repeat the rule for the next same key words. Sure, if I import all the data in MMA, it is ok, but how to import selected information in MMA, at least not clear for me now. Thanks a lot for your support in advance
